This is perfectly normal and expected.

Tiny comment:

Have you tried the latest Buildbot builds?
I had a similar bug that was fixed some time ago: https://developer.blender.org/T52479

OIC, thanks for your fast response.

Confirmed on my side.

Obviously a duplicate of https://developer.blender.org/T52687

Thanks for confirming this. Yes, it "works" when scaling first, but in my case all the filters were set to a specific look and I was about to start the playout for the final delivery of several shots in 4k when all of a sudden I noticed this bug.
In the end I started resizing all of the render pictures with Fusion.

Thanks, Sergey!

Just tried it and it helps a lot!

Thanks Bastien for instantly fixing the linking bug and updating the "Purge All" button with important information! 😄

Nice you can reproduce it and thanks for your quick reaction.

I was about to post the same report here. :)
I noticed it after I completely cleaned a blend file but it still took ages to load. The Outliner didn't show anything but the Group still existed and caused a linked file to be loaded although it wasn't used anymore.

Thanks for your answer, Vuk. I didn't even know that one could find every single pixel of an image in the Outliner... crazy ;)

I don't know if this helps in any way but if I enable the new dependency graph (--enable-new-depsgraph) the scene load time goes from several minutes to a mere 5 seconds.
The Outliner performance problems persist though.

Thanks Corey for having a look at this. I hope you find something to improve this as it's a major bottleneck here right now.

I just tried if this new fix also gets rid of these artifacts but it doesn't: https://developer.blender.org/T51681

Wow! That looks great. I don't have much time to test all kinds of combinations but following the repro steps in this bug report gave me the results I expected:

Yes, I noticed that too. The bundled EXR environment seems to be a tough one. The tiny sun disk is at something around 50000 RGB!
But on the other hand I want / need the "power" of this sun to give me bright highlights and sharp shadows, clamping would be my last resort.
I wonder why Branched PT isn't giving me artifacts.

Confirmed. I was just about to report it here as well ;)

Sorry, can't help you because I don't know what kind of modifiers you try to apply or what your scene looks like but I can translate that German term to English for the other 99% of users here:

I'm afraid something went wrong here. I get an instant crash of Blender as soon as I start tracking, no matter if I use Autotrack or a single manually placed tracker.
The latest Buildbot build that doesn't contain this commit is not crashing.

All fine here. Latest builds. Win x64.

At least with the current Buildbot builds Alembic export always crashes as soon as I use "Simple" or "Interpolated" children no matter what I set the "Display" amount to.

I can confirm it with the very latest Buildbot build.

There seems to be a syntax error in line 40 of filter_features_sse.h

No, sorry, no backtrace. I'm not a coder, I'm just glad I can compile Blender myself ;)

I justed tested it again and found that my own VS2015 builds and the official Buildbot VS2015 builds crash while the VS2013 builds from the Buildbot don't.

This EXR coming with this scene is known to contain NaNs. Saving it to HDR format "fixes" this. But even saving it as a new EXR (I tried 16bit half-float with ZIPS compression) got rid of the black boxes.
If you load the original environment EXR into Natron it displays a yellow warning that it replaced some NaNs with white.

According to the build number in the splashscreen, yes.
And the bmesh_bevel.c source also contains the latest changes.

Thanks for taking care of this. I just compiled the very latest master and the Blenderman.blend still crashes Blender here.

All 2.8 Buildbot builds also crash.

You're a wizard! Thanks for this very quick fix!

OMG! It crashed in my own latest build and it still crashes in the current Buildbot builds but it looks like Sergey just fixed it while I was typing the bug report!!!

Ah, that's good to know, Sergey.

The Blenderman file is still crashing all the Buildbot builds on opening while official 2.78c can open it. Is this a regression of some sort?

I just compiled the latest version and the fix is working perfectly! :)

Hi Howard,

Wow! Thanks for your quick help! :)

Wow! That was fast! :D
