Bug ID: 457851
Summary: Wayland: Screen corruption in full screen applications
on secondary iGPU
Product: kwin
Version: 5.25.4
Platform: Gentoo Packages
OS: Linux
Status: REPORTED
Severity: normal
Priority: NOR
Component: wayland-generic
Assignee: kwin-bugs-n...@kde.org
Reporter: andrewammerl...@gentoo.org
CC: xaver.h...@gmail.com
Target Milestone: ---
SUMMARY
Applications that go into full screen mode are not rendered correctly if the
window is on a display connected to the secondary integrated Intel GPU. The
screen gets corrupted, weird lines and colours all over, I would make a
screenshot but the window looks fine in the screenshot. Full screen does work
when the window is on a display connected to the primary AMD GPU. Most, but not
all, applications are affected. Konsole works fine in full screen, VLC and
Firefox do not.
STEPS TO REPRODUCE
1. Start Plasma Wayland session
2. Open VLC
3. Press F11 to make the window full screen
OBSERVED RESULT
Screen is corrupted and unusable.
EXPECTED RESULT
The display shows the window in full screen mode without any screen corruption
