SUMMARY Whenever opening Steam games in fullscreen with X11, one of my monitors turns black until mousing over to it and the windows on that monitor behind the active window turns transparent. I have tried this on both my laptop (with nvidia gpu) and desktop (amdgpu) STEPS TO REPRODUCE: 1. Add a 2nd display to setup 2. Start Plasma with X11 3. Open any game in fullscreen mode OBSERVED RESULT Second display goes black until mousing over it EXPECTED RESULT Game opens and nothing besides this happens SOFTWARE/OS VERSIONS Linux/KDE Plasma: Fedora 36 (Nobara) KDE 5.24.5 (available in About System) KDE Plasma Version: 5.24.5 KDE Frameworks Version: 5.93.0 Qt Version: 5.15.3 ADDITIONAL INFORMATION Observed both on latest Mesa-git and latest stable Mesa. Have reinstalled system and I have tested with no packages installed besides standard nobara install - just games (eg. Slay The Spire, Humankind, etc.) Observed on both RX 6700 XT GPU and 1660 TI MaxQ (ROG G14)
This is rare. I'm have been using Steam with plasma 5.24.x and now 5.25.0. I don't have this issue. The active window goes to full screen and other doesnt change at all. However I use always the external mornitor for playing. my setup is Kubuntu 21.10 Plasma 5.25.0 X11 Nvidia GPU. Regards Galder
