Bug ID: 461042
Summary: Plasma windows/mouse lag or stutter when theme on
Wayland
Classification: Plasma
Product: kwin
Version: 5.25.5
Platform: Other
OS: Linux
Status: REPORTED
Severity: normal
Priority: NOR
Component: aurorae
Assignee: [email protected]
Reporter: [email protected]
Target Milestone: ---
When using Breeze global theme everything is running smoothly. Upon changing
window decoration or application style to kvantum, all windows and mouse start
to stutter or lag a bit. Animations look as if the framerate dropped. This
only occurs in Wayland. Everything in x11 is working fine.

STEPS TO REPRODUCE
1.Be in Wayland
2. Install global theme whitesur
3. Install and use kvantum
4. Change global theme to whitesure or just change window decorations to
whitesur
OBSERVED RESULT
Mouse pointer movement, animations and windows stutter or lag upon movement.
Looks as if refresh rate was wrong or framepacing incorrect.
EXPECTED RESULT
Movement lags or stutters
SOFTWARE/OS VERSIONS

Linux/KDE Plasma:

KDE Plasma Version: 5.25.5
KDE Frameworks Version: 5.98.0

ADDITIONAL INFORMATION
I connected a second monitor with the same refresh rate (60hz) and everything
was running fine on the monitor. Increased the refresh rate on the monitor to
120hz and ran even better. On main display (laptop) all motion was stuttery.
Have not tried other aurorae themes. Everything seems to work normal when
reverting to Breeze theme, but will come back even if I change just the window
decoration.
-I tried changing compositor settings, animation speed and nothing worked.
-Tried changing scaling back to normal to see if that was the issue and it did
not fix it.
-I tried to replicate the bug in Fedora 36 KDE and it was not present there.
