Bug ID: 502902
Summary: games renders only when window is not in focus
Classification: Plasma
Product: kwin
Version: 6.3.4
Platform: Arch Linux
OS: Linux
Status: REPORTED
Severity: normal
Priority: NOR
Component: wayland-generic
Assignee: kwin-bugs-n...@kde.org
Reporter: benato.deni...@gmail.com
Target Milestone: ---
SUMMARY
I have been chasing an issue:
https://gitlab.freedesktop.org/mesa/mesa/-/issues/12744 that led me here.
Rendering certain games with an amdgpu on the screen attached to it makes it
behave EXACTLY as if
if (window_in_focus) {} else {render()}
so the exact opposite of how it should work. Moving the window on another
screen (connected to the igpu) solves the issue.
STEPS TO REPRODUCE
Assuming you have a system with an igpu and a gpu (can be internal. oculink or
thunderbolt)
1. Start the monster hunter wilds benchmark (free on steam) using the amdgpu
rendering on the attached screen
2. Reproduced
OBSERVED RESULT
game changes frame only when not in focus
EXPECTED RESULT
game changes frame regardless of being in focus
SOFTWARE/OS VERSIONS
All plasma 6+ versions are affected. 5 are untested. Happens on every distro I
tested. This issue was present in gnome too but they fixed it recently.
