System Information
Operating system: Fedora 33
Graphics card: Intel HD Graphics 520 (Mesa 20.2.4)

Blender Version
Broken: 2.91
Worked: 2.90.1

Short description of error
Blender randomly freeze entire graphics system. After freezing, last 2 frames is flickering if you move mouse. I can even save my work with CTRL+S, but after that i need to restart my computer. Setting INTEL_DEBUG=reemit environment variable fixes the issue.

Exact steps for others to reproduce the error
Method 1
Add a few keyframes.
Scroll up and down in the NLA editor.

Method 2

Just do something, even in Solid view, even in Video Sequence editor. I don't know how to reproduce, it happens after 10 minutes of work. Also i notice some glitches in VSE with image strips. Also bug with Depth of Field was fixed in this version, probably this fix relate to this bug.

Glitches in the VSE were also reported in #83318. If the system freezes outside of Blender as well, it seems like the issue is in the graphics driver and not (just) Blender itself.

You could try to run Blender with debug flags and upload the log files when the issue happens again.

./blender --debug --debug-gpu > ~/blender_debug_output.txt 2>&1

It happens only in Blender 2.91, Blender 2.90.1 works fine up to few hours (didn't test for more).

@scaled Is the freeze limited to Blender or does it affect the entire OS? Does this problem only happen with a particular project?

Freezing happens only if i use Blender 2.91. But after 10 minutes of work screen become unresponsible in entire OS, but keyboard and shortcuts works. Also, after saving work and closing blender with ALT+F4 screen doesn't return to normal state and i need to reboot my PC.

I don't remember, usually i working on my latest big project with many libraries and animation data. But i can test this bug with another project later.

@scaled Since this affects the OS as a whole, this appears to be a problem with your graphics driver and not something that we can fix.

@scaled Have you been able to check if upgrading or downgrading to a previous version of the driver fixed the issue for you?

I upgraded driver today and nothing changed. I also tried another blender project, without VSE in my workspace, leave it compile my Eevee shaders while browsing internet and my system was crashed too. Firstly, after compiling latest Blender it crashed my system after few minutes when i tried to record some things with OBS while exploring my World.blend. I thought that it OBS, but it happens again without OBS and other programs.
Usually i use X11, but recently i compiled latest Blender from git (2.92.0 Alpha) with native Wayland support and bug appears too. 2.90 works incredibly stable, but 2.91 don't =(((
I think that this bug is some sort of video memory leak, but i don't know how to check my video memory, Blender don't show it too.

I compiled Blender 2.92 Alpha with this CMake flags and it works just fine under X11.
WITH_GHOST_WAYLAND = YES
WITH_XR_OPENXR = NO
WITH_GL_EGL = YES
WITH_CYCLES_NATIVE_ONLY = YES
WITH_CYCLES_DEVICE_CUDA = NO
WITH_CYCLES_DEVICE_OPTIX = NO
WITH_CYCLES_DEVICE_OPENCL = NO
WITH_INPUT_NDOF = NO

Also i added -march=native to CMAKE_C_FLAGS and CMAKE_CXX_FLAGS.

I can reproduce bug even more easily. You just need to scroll NLA editor to freeze system in HD Graphics 520, Mesa 20.3.3.
Let's rename issue to "Entire system freezing while using NLA in Blender 2.91 and newer"

Cant reproduce any of this, seems to be Mesa bound?

Are you getting this on any machine not running Mesa?

Update. I notice few things. Firstly, INTEL_DEBUG=reemit environment varriable resolves the problem, but in cost 50% performance in heavy scenes.
Also when you trying to capture blender 2.91 or newer with this tool https://github.com/nowrep/obs-vkcapture , you get strange picture. With Blender 2.90 capture works just fine.
