Bug ID: 507428
Summary: [Regression] Fullscreen doesn't display properly in
some Linux-native games when fractional scaling is
used since Plasma 6.4.0
Classification: Plasma
Product: kwin
Version First 6.4.0
Reported In:

OS: Linux
Status: REPORTED

The game when started in fullscreen with 125% scaling
After upgrading to Plasma 6.4, when using Wayland, I started having a problem
where some games that run natively on Linux display weirdly in fullscreen, more
precisely the game window shows up at the left side with the rest of the
fullscreen window being black. This doesn't happen if I scale the screen to
100%, then start the game, after which I could set the scaling back to the
desired value above 100% to work around the problem completely. I would prefer
not to have to do this as 100% scaling is too small for me on my 1440p monitor.
Steps to reproduce:
1. Enable fractional scaling in Plasma 6.4.0 or later
2. Open a Linux-native game in fullscreen which is affected by this
issue(doesn't seem to happen with all games)
Observed result:
The game opens, but the window displays smaller and on the left side of the
screen.
Expected result:
The game displays on the entire screen.
Software/ OS versions:
Linux: Fedora 42 kernel 6.15.7
KDE Plasma Version: 6.4.0
KDE Frameworks Version: 6.16.0
Qt Version: 6.9.1
Additional information:
Unlike in the previous versions of Plasma, the same game runs natively on
Wayland instead of through XWayland and can't be forced to run through
XWayland(as trying to do so results in the game failing to launch).
