Public bug reported:
I believe I've found a regression in Ubuntu 19.10 Eoan concerning a
Steam game.
Start an Ubuntu session on Xorg and try to play Counter Strike: Global
Offensive. The screen stutters, skips frames, becomes glitchy and
ultimately unresponsive. It doesn't respond to ALT+F4, doesn't let me
open the Activities overlay and ALT+TAB also does nothing. However, the
mouse pointer still works and I can still hear some delayed sound
effects from hover events in the game.
My system logs are being spammed with errors related to the game. Take a
look at the attachments.
On a Wayland session, the game runs normally. I haven't tested other
games yet.
I believe a recent kernel update did this. It was version
5.3.0-19-generic. Before that update I could play CS:GO on Xorg. This
problem is also reproducible on the latest Fedora Workstation, which
uses a slightly newer kernel.
Specs:
Graphics: AMD RX 560 (AMDGPU, open source)
CPU: Intel Core i3-8100
Ubuntu 19.10 Eoan (GNOME, fresh install)
I tried to use `apport-bug steam` but it failed saying the package isn't
installed, which doesn't make sense. See attachments.
