SUMMARY Black screen flickering when starting a game on Steam after screen/mine has turn off one time Only a single screen is in use (no multi monitors issue) Tried to disable gsync with nvidia-setting, force pipeline, reconfigure xorg.conf file Tested with compositor disabled STEPS TO REPRODUCE 1. Switch screen with power button 2. Switch it back on 3. Start a game in Steam (tested with Deathloop but does the same on Rocket League) No issue after a reboot for example. Only after a screen turn off (manually or through suspend) OBSERVED RESULT Flickering Black screen on start up. Cannot interact with the game window (I have a video if you want to see). We can still hear game sound and rendering once in a while but not interactable. I think it is a Kwin issue because of a log in journalctl I find only when I have the issue: Feb 02 23:10:18 arch-jimbo kwin_x11[935]: kwin_core: Failed to focus 0x340008d (error 8) Feb 02 23:10:18 arch-jimbo kwin_x11[935]: kwin_core: Failed to restore focus.

Activating 0x3400021 it can be printed if kwin tries to focus a window but it's been closed in meanwhile (communication between kwin and xorg is asynchronous). Not sure how kwin could cause it or whether it's a driver bug. Can you check whether the issue is reproducible when running another window manager, e.g. openbox systemctl stop --user plasma-kwin_x11 openbox --replace after you're done systemctl restart --user plasma-kwin_x11

Trying with openbox still reproduce it. Thanks for your time. Closing this
For posterity: https://github.com/ValveSoftware/steam-for-linux/issues/7866#issuecomment-1422916056 It was indeed an error with Nvidia driver. Disabling gsync at the monitor (not in nvidia-settings) did the trick
