Bug ID: 527198
Summary: KWin Wayland compositor stutters when transitioning to
power options menu while active DXVK/Bottles/Xwayland
window is open and in focus
Classification: Plasma
Product: kwin
Version First 6.8.0
Reported In:
Platform: CachyOS
OS: Linux
Status: REPORTED
Severity: normal
Priority: NOR
Component: wayland-generic
Assignee: [email protected]
Reporter: [email protected]
Target Milestone: ---
DESCRIPTION
Having trouble with VirtualDJ and Bottles causing the logout screen to lag
whenever summoning the power options menu. Countdown and button feedback tends
to lag, or the transition to the screen may stutter or hang for roughly 2 or
more seconds.
STEPS TO REPRODUCE
1. Open VirtualDJ via Bottles, unminimized and in focus
2. Use the power button to get to the power menu or click any power option
(Restart, Shut Down, Log Off, etc...)
3. Observe the transition to the logout screen, compositor holds up for a
while.
OBSERVED RESULT
Screen fades to black, then stutters briefly while attempting to fade in the
logout greeter (takes roughly 2 seconds) to fully fade in.
EXPECTED RESULT
Logout greeter should smoothly fade into view without causing compositor
stutters.

ADDITIONAL INFORMATION
Minimizing the window puts a Band-Aid on the issue, causing the lag to stop
Hovering over buttons exacerbates the lag (countdown moves faster or freezes)
