Hi. I was testing a bit of animation in 2.8, mainly things that fall, and I found the big "Frame number indicator" in new Timeline somewhat distracting when playing animation in viewport. I have disabled "Show Frame number indicator" for Timeline (that is something that I will surely configure by default for me in 2.8). The problem here is that for some users "Frame number indicator" could be useful in Dope Sheet mode (and other modes) since frames are not shown in the bar like in Timeline mode.
Just commenting on that experience. Thank you very much for your hard work.

Sorry, maybe my bad English (again). I just wanted to contribute that I'm in Linux and it works well here.
Blender currently no warns into GUI when an image is not found for some reason, right? (ex. if it changed name or location, Blender access rights to the location are not allowed, etc). It would be nice if UI indicated it in some way (red/purple highlighted in Image name field for example).

Sorry, I misinterpreted. Thanks for the clarification.
I completely agree with Alberto.
But, does this pretend to be behavior by default? If so, I'm a little confused right now. I understood that there would be changes to improve consistency between all the modes/editors within the same Blender, and make things easier for new users who use Blender as the first 3D program ever, not to satisfy users coming from other programs. I entered/know the 3D world with Blender as firts program. Then I have tried other programs and I think Blender has the best mode for viewport navigation with mouse button wheel (and the pen on a graphic tablet). Only noticed the problem of the LMB select that we all know.
Would a "Smart" mode be possible to position 3D Cursor?. For example with "Smart" mode enabled, when left button clicking on an object or an empty, it automatically positions 3D Cursor in Object origin or exactly on the empty. In Edit mode, if you left click on a vertex or near a vertex (just like RMB selection works) then 3D cursor is automatically positioned on that vertex. The same for edges or faces.
Also Smart mode to position the cursor on Grid Floor, especially in Ortho view.
In my case, the only time I use LMB to directly position cursor in 3D View, is when I want to remove of my view 3D Cursor bothering about where I am working. Otherwise, I always need more precision, this is to first Select item and then Snap Cursor to... Then Smart mode would save those tedious steps.

LazyDodo , Sorry, I had not paid attention to your message.
Supposedly, that problem was solved (reverted) for 2.79b?. This problem also occurs in Blender 2.79b, here the system graph while Blender is hanging (big brush and spacing = 1%):

Michael, Download that build labeled with 2.79, not 2.8.

Render looks great and using only 47 samples. Thanks Brecht.
It seems that Roger will be able to save a lot of render time using default value of step size.
Unfortunately it seems that Buildbot is having problems to build Windows versions.

Here Linux, just making observations. In Blender 2.79 official release I can see the black hole and a lot of noise around it. Increasing light paths > Max Transparency to 16 the black hole improves a bit, still a lot of noise around.
Mar 24 2018
Sorry if I introduced confusion to the report.
Alberto, the point is that this worked as Daniel described until 2.79 release inclusive and this may have been useful for many users. Then something changed.
I do not know if it has been mentioned, but for the value to be remembered in 2.79 and earlier it is necessary to enter values from context menu first (T panel or F6). If you did not enter the value from the context menu, the last value is not applied when you apply bevel again (at least in Linux). So suppose you applied Bevel with amount=0.5 on an edge by modifying the value from the context menu. Then, select another edge and you apply Bevel=1 but enter it from numpad keyboard (Ctrl B - 1). Suppose that you select another edge and apply Bevel. The value 1 entered from the keyboard is not remembered, instead 0.5 is still remembered and applied.

I was just testing eevee with Classroom scene a while ago. At some point I added the reflection plane and saved the file. Then working with the scene I realized that Blender crash when trying to eliminate the reflection plane. So I cleaned all the classroom scene elements leaving only the problematic reflection plane to share the file here.
Currently I try to recreate the problem with the same scene using current version of Blender 2.8 and everything works fine, Blender does not crash.
So maybe it was just because I was working with a very early stage of Blender 2.8 that time, and something was corrupted by adding the reflection plane.
You feel free to leave this report closed.

@LazyDodo (LazyDodo). Maybe just Linux issue? My system monitor graphic with Blender 2.79a is basically a permanent horizontal line at approximately 13.5 GB :)
Just in case, using 4.15 linux kernel here.
I am able to reproduce the problem with Blender 2.79a official release and this scene:

I was just trying to get a quick background for the BA weekend challenge. I'm not even sure if those nodes are being used well here, and neither is it common to use it in World nodes. If you ask me, I prefer speed :) . But I have no idea, perhaps the problem that jumped here could affect other cases, and since we have GPU + CPU combined render, differences are more sensitive.
The nodes in Material render similar on GPU and CPU:

I was unable to reproduce the problem with this file:
Open "quick_smoke.blend" file. Press "Bake" button. You save the file again (File > Save). Close Blender. You open the "quick_smoke.blend" file again. Baked simulation will remain there as long as you do not delete the folder named "blendcache_quick_smoke" that had been created on the same path where you saved .blend file.

I have read before that the mere fact of having installed some GPU overclocking application can bring conflicts with Blender, even for CPU render. I say this because I read above about MSI Afterburner. So just in case to do reliable tests, if you have any of them installed (MSI Afterburner, ASUS GPU Tweak, etc.), completely remove the application.

Maybe new Russian Roulette method helped here?
Just to mention just in case. If you increase Lamp size (1 for example), some weird things still happen in this scene using resent blender from buildbot:

Regarding the comment above, I'm not sure how this could be OS dependent. But I can still reproduce the problem in Linux, blender from buildbot 11a9434c2de

I agree with 'bigbad' about "They are for testers and user feedback" part in that message can be confusing, and users could spend time making reports that will then be closed. Maybe delete that part of the message, and even better than that expressly clarify that Blender 2.8 is not yet in a stage in which user reports are accepted.

For "bmw27_cpu.blend" scene downloaded from blender.org (not the BMW27.blend scene belonging to Blenderartists forum), the time you get 2 m 32 s looks to me very little time for an 8-threads i7 CPU. 5 m 51 s looks to me more feasible. What is the exact model of the CPU? Did you compare side by side the resulting images to see if they look the same?

Yes, that nodes setup from the link makes a lot more sense. I just thought that to do something like that could be as easy as mixing two Emission Nodes connected to Volume, and controlling the weight with Layer Weight. I am very bad with nodes, my mistake.
Ok, sorry, Perhaps obvious to experienced people, but Layer Weight Node documentation did not clarify anything about not usefull for Volume. Now I have just found the right way to do what I intended to do in cycles:
Here I mention some other examples where I encounter problems with volumetrics. I am not good with nodes, so I apologize if this is due to my mistakes with configuration.
In the following example there are differences between GPU and CPU render:

Some tests. The effect is also visible with pure metalic Principled BSDF connected to eevee material output. Glossy BSDF connected to eevee material output looks very similar to Cycles (Glossy and Principled on Cycles).

It seems Shadow Catcher is working well in my tests, it seems to react well to the variation of different lights:
Edit: corrected the previous scene (had forgotten to select to repeat with offset in one of the modifiers):
Mar 17 2017
Yes, it is. That's what I mean when I say I've seen this kind of problem before. So let's wait for what cycles developers say about this.
Whenever you see this kind of strange problems related to slowness in certain frames or frame intervals, you should see if this is related to Motion Blur enabled.
I have seen other times Motion Blur cause these kind of problems. I do not know if this is due to a bug or just it is one of those known problems that usually have Motion Blur in Blender.
Mar 15 2017
This is working now.
I think that with 'OpenGL depth picking' it's going to be the first time I'll be able to use Blender with intel on Linux.

@Lukas Stockner (lukasstockner97) , This is the story: I was having these crashes when trying to use image as plane with my photos revealed and exported from Darktable (tif format). The crash was always reproducible, I always did the tests without packing the tif in .blend file.
So then I had decided to report the problem, and because the problem does not occur with any tif, I decide to pack the tif into .blend file to include in the report. So before sending the file I do the test again, and, wait a minute!... Is there when I find that packed tif does not produce the crash.
So yes, the problem basically happened with the original file.

Thanks Lucas for the clear report and thank Sergey for the fix.
This problem had given me more of a headache with some addons, and some people out there having this problem but without them knowing exactly why.
Oct 10 2016
Not directly related to the problem you mention, but at least you can use GPU compute until you can solve the problem. If you are using nvidia drivers installed from repos, I recently read that in Linux Mint you still need to install 'nvidia-modprobe' package. You look for that package, install it and reboot the system. Remember that you also must have installed 'libcuda1' related package. And of course you should use official Blender downloaded from official Blender 3D website which include precompiled CUDA kernels (tar.bz2 file for Linux). Extract to a folder and run there 'blender' file.
You can search about 'nvidia-modprobe' and Blender in Google, there is much written.

So who should open the new report about bmesh boolean modifier?. I really do not know how to open this report and what information provide there.

Thank you sergey.
This new patch seems to be working much better. I've tried it with my file with different sizes and strength in lamps and shadows match pretty well in the plane with shadow catcher and in the plane without shadow catcher.
I have also tried the file 'shadow_catcher_submit_01.blend' by hype, and the blue emmiter ring no longer have much influence on the total shading, which is good. In this scene I just noticed that there are some reflections in the plane with Displace Modifier under the hard black shadow, and I'm not sure about whether this should be so. Select the Sun lamp, set Size=0, and you start to move the Strength smoothly from 0 to 10 while you see the shadow changes in rendered view preview. It looks a little weird for me, but maybe that's as it should be.
I recently discovered this about the Shadow Catcher and I'm not good at compositing, then sorry if my .blend file have errors.
My concern is whether the intensity of the shadows obtained on the plane with shadow catcher should be similar to that obtained on a plane with difuse material and without shadow catcher. Here in this scene render shadow catcher when you just open and render image. If you enable the first render layer and disables the other three, you get the scene with shadow over the plane without shadow catcher (I guess):

Yes, but if this was a particular problem with the graphics tablet like this I had, then the problem should be present in texture paint, curve draw and GP (exactly like the problem I had). Sorry if I intruded on the report, I just requetsed the test to discard that this could be a general problem with the graphics tablet in Blender or system, because I had seen those similar artifacts that I had that time.
To see if it is a problem with the graphics tablet on your OS. Could you try if you have the same kind of problems in .blend files I had shared here?
Jul 28 2016
Working well now.
Jul 26 2016
I have compiled from master and I have not been able to reproduce the problem anymore, it is working very well.
Jul 20 2016
Ok, I see. Thank you.
I really do not know much about sculpt in Blender, so I really do not know exactly how it should be the behavior of the brush. So I have some questions.
I have compiled Blender from master (690063e) and when open the test file I noticed that "Accumulate" option is enabled by default now. If I disable "Accumulate" before beginning to sculpt, then the behavior is the same as mentioned earlier in this report, making that kind of bump in the first stroke. So this should be that way when "Accumulate" is disabled?

The user can not edit the title, right?

Perhaps I have not been clear here. Apparently you refer to World (HDRi environment texture) strength. You do not touch that value in the scene, you leave that value to 1. With "strength=0" I am referring to the lamp selected by default when you open the scene. You just open the scene and render in Belnder from master (Do not forget to load the HDRi). Did you not get a resulting image like the first image I've shared?. I think it should look like the second image I obtained in Blender 2.77a.
I know, there is no logical reason to put there a lamp with strenght=0. But anyway I do not see any reason to get a resulting image like the obtained from master (first image).
Regarding whether this occurs in CPU/GPU, master/buildbot:
On my machine the render looks good with 2.77a (abf6f08):
Sorry, this happens with any type of lamp with strength=0

Stefan Werner, Do you have in your OS the virtual memory located on a 7200 rpm disk?
Sorry if I misunderstood, but your system freeze reminds me of those I have in Linux when the system begins to fill the Swap intensively on a slow disk (as one of 7200rpm). That always happens in Linux when intensively fills the swap, swap management is not good on Linux (you look in google how a lot of people try to avoid using the swap by configuring swappiness).
What I mean is that if the freeze on your OS was due to the intensive use of the swap, then maybe in a system with more RAM the problem does not occur.

With Cosmos Laundromat default scene (for CPU benchmark) I still have CUDA out of memory error. I guess I need more than 16 GB of RAM for patch works in this scene?
