Comment 2 Mikhail 2020-12-09 19:52:11 UTC
Yes I know that this commit is not culprit here. I suppose here is blame new GCC 11. I am every day compile mesa git and after the GCC 11 was came to my computer then all graphical application started crashing too with fresh builded mesa.

Comment 4 Chad King 2020-12-14 02:27:45 UTC
Hi, ran into this as well on my RX 6800. Ended up downgrading to mesa 20.3.0-1, thanks for the info.

Comment 5 Fedora Blocker Bugs Application 2020-12-20 21:13:25 UTC
Proposed as a Blocker and Freeze Exception for 34-beta by Fedora user mikhail using the blocker tracking app because:

 Because gnome-shell will not run on computers with Radeon GPU (checked on Radeon VII and 6800) after users upgraded to Fedora 34.

Comment 6 Mikhail 2020-12-29 20:40:16 UTC
The problem will gone if mesa would compiled with gcc-11.0.0-0.11.fc34.
So please rebuild mesa and put new build in repo.

Comment 7 Adam Williamson 2021-01-02 19:59:39 UTC
There was a build on Dec 31:

so is the bug fixed now?

(I thought we built mesa with llvm not gcc...)

Comment 8 Mikhail 2021-01-02 22:58:04 UTC
> There was a build on Dec 31:

Yes, the build 20.3.2-1.fc34  working well as expected on Radeon GPUs.

This is isn't it.
You can to sure here:
