Mircea Kitsune (mirceakitsune) closed T59969: Blender 2.8 triggers GPU lockup when entering Edit Mode as Resolved.

This does seem to have been solved in either the latest Blender 2.8 build or Mesa version: I can now go into Edit Mode on meshes with a lot of vertices, no longer getting either the graphical corruption or any GPU crashes.

In the meantime I've preformed a test which was recommended to me by another user. The crash seems to be unaffected by booting with either "amdgpu.dc=0" or "amdgpu.dc=1" and will occur identically in both cases.

Sorry for not being aware of 2.8 reports being closed. I was going to report something else for this version, but now I know to wait until 2.8 reports are open.

Mircea Kitsune (mirceakitsune) added a comment to T54006: Glass surfaces are treated as opaque by shadow rays.

I'd still be curious why shadow rays can't be probabilistically terminated upon touching a glass shader, based on the transparency value of the glass at that pixel. Even if it's based on estimation and not fully realistic, couldn't at least an option for that be added in the meantime?

Mircea Kitsune (mirceakitsune) added a comment to T51911: Blender crashes when rendering on GPU with RadeonSI / GCN 1.0 card.

I understand... thank you for clarifying. It's especially sad that Blender can't get better GPU Compute support for Mesa & the radeon driver; With Blender being open-source, many of us use Linux over Windows, and most of those will avoid all proprietary software including proprietary video drivers (for ATI cards, fglrx). Same reason why I have an AMD card instead of Nvidia... IIRC Cuda is proprietary and not available in Nouveau, but OpenCL is an open-source standard.

Mircea Kitsune (mirceakitsune) added a comment to T51911: Blender crashes when rendering on GPU with RadeonSI / GCN 1.0 card.

As for support, I remember once reading that the official stance was "all GCN cards are supported, but we can't guarantee that cards not officially tested and listed will work". I actually bought this video card with Blender in mind, hoping that anything modern and GCN enabled was a safe option. Blender has been very picky and "discriminatory" when it comes to video cards and allowing GPU rendering, with seemingly just a few users privileged to have this feature (at least for AMD / OpenCL)... therefore I hope this can be further investigated, and not closed with a simple "we don't support this card at this time" note.

Thank you for those suggestions, and pointing out that debug parameter. I gave it a try, and found some differences with two debug options:

Mircea Kitsune (mirceakitsune) added a comment to T48038: Blender permanently increases in memory usage with each render, when motion blur is enabled.

Today I tried to render my scenes with fresh Blender settings (new ~/.config/blender/2.77 directory). To my surprise, the issue went away entirely! Blender also uses a lot less memory at startup and while rendering now.

Very well. This was actually easier than I thought: A simple Suzanne head with a subsurf of 6 is enough to visibly trigger the problem. These are the results I'm getting with it:

Mircea Kitsune (mirceakitsune) added a comment to D808: Adaptive stopping and sample distribution for Cycles.

Thanks for the clarification! Although I wanted to hope they weren't accurate or that this might change, several people stated that this patch does too little to improve performance in production scenes. If a whole new implementation is needed to get the best effect, I can agree that's better, even if it takes a bit longer to happen. Otherwise I'm familiar with being busy with multiple software project, and not being able to get as much as you wish done... it would be wrong to expect too much, though I do hope we might see something interesting during 2016 if all goes well. Thank you and good luck!

Somehow I predicted this was going to happen... hence why I kept poking the Blender team about getting this done sooner, before it got abandoned. If an alternative is in the works however, not all hope is lost. Any links to the new project please?

Is there any news on when we might expect this to enter Blender, even as an Experimental feature? As someone who strongly struggles with noise vs. render times (no GPU support here) I'm eagerly waiting for it to happen already! Taking the forum thread into account, this has been around for over an year now.

Mircea Kitsune (mirceakitsune) added a comment to T45715: Blender crashes when creating Environment Map textures in Multi-View mode.

That should not be a huge problem, and it's probably the only working solution to begin with. First of all because you'd get double stereoscopy if both the 3D surface and envmap texture are stereoscopic, and envmaps are typically cubes so things like eye convergence are probably not applicable. I don't have Blender set up to compile here, so I'll try the fix once 2.75b or 2.76 are out. Thank you for solving this.

The issue is so quick to reproduce, I figured one wouldn't be needed. But here it is: Simply press F12 and Blender should crash.

Mircea Kitsune (mirceakitsune) added a comment to T43599: Visual glitches occur on certain models, in Game Engine and possibly the viewport.

I'm not completely certain if it's GE only, or affects the viewport as well. In the example blend I posted, it only happens in GE. But in different cases, smooth shading doesn't work on certain meshes in the viewport, and flickers if you look from certain angles. The issues look quite similar, and I can't tell if they have the same root cause.

A third person confirmed the issue on the #gameblender IRC. They didn't mention as much as @Sybren A. Stüvel (sybren)... just that they remember noticing the issue in 2.68, which means it might be older than I initially thought.

Mircea Kitsune (mirceakitsune) added a comment to T40844: Noise textures not renewed when used in composite nodes.

Thank you, I'll keep this alternative in mind. Still, I prefer the noise texture for simulating static noise, since it feels like it gives the best effect and precisely what I need. As long as this texture will exist and is possible to use of course... I can understand if development changes might make it unusable in the future.
