I was playing GTA V and changed the volume while in game. Xorg crashed with the following backtrace:

Here's a better backtrace:

It seems to crash when the game regains focus.

Please attach the corresponding Xorg log file and the output of xrandr --prop.

Comment 3 Ernst Sjöstrand 2018-12-18 12:02:43 UTC

I had a crash a few weeks ago when changing volume during Vulkan fullscreen gaming and using the Gnome desktop (which pops up transparent window on top).

It looked like this: https://paste.ubuntu.com/p/FD9dDx68kd/

But I had a slightly outdated version of amdgpu ddx and got this reply:

MrCooper: ernstp: make sure you have all commits from the master branch, in particular https://gitlab.freedesktop.org/xorg/driver/xf86-video-amdgpu/commit/51ba6dddee40c3688d4c7b12eabeab516ed153b7 might help for that crash 

But I guess you have that commit now...

Comment 4 Michel Dänzer 2018-12-18 16:08:35 UTC

Does https://gitlab.freedesktop.org/xorg/driver/xf86-video-amdgpu/merge_requests/19 (the first patch specifically) fix it?

Comment 5 Clément Guérin 2018-12-19 05:25:31 UTC

I can confirm that MR !19 fixes it. Thanks for looking into this!

Comment 6 Michel Dänzer 2018-12-20 09:32:07 UTC

Now merged, thanks for the report and testing.
