It seems that the crash occurs inside some gl function called in detect_mip_render_workaround.
@fclem, any idea what change in 171b36683a may have caused this problem?

Thanks for the report. This GPU is below the minimum requirements for Blender, so there is no longer support for it. https://www.blender.org/download/requirements/

Installing the latest graphics driver sometimes helps to make such GPUs work, see here for more information. https://docs.blender.org/manual/en/dev/troubleshooting/gpu/index.html

If that doesn't help, you can use Blender 2.79: https://www.blender.org/download/previous-versions/

One thing to note is that running using --debug-gpu-forceworkarounds or using the associated .bat file to launch blender will bypass this test. So you should be running fine.

However I don't know how/if we should always bypass this test for those hardware.

Greetings, I checked the problem a bit since I also use a deprecated and unsupported Radeon gpu. I hope it's not a problem to comment on a closed issue.

The crash happens on glClear of detect_mip_render_workaround. As a workaround, I moved the check to the bottom so it's ran only if the flag is not set. Also set the flag for the Radeon driver. This is enough to avoid the startup crash and keep the cards usable before being blacklisted. Although since it's a driver problem there might be a crash elsewhere still, but I can see the cube and render it with cycles again! Yay!

Get the source code, apply diff, compile and voilà! I'll see about making a 2.91.0 build with the fix applied and post it, since compiling is quite involved with a big download and taking a loooong time.

Ok. Thanks!)

Alright, here's a build for 2.91.0. Just backup the exe file in your install directory and extract this one there.
