Product: kwin
Version: 5.26.1

OS: Linux

Resizing windows with different animation speeds
SUMMARY
The speed of resizing a window seems to be affected by the animation speed set
in system settings. When the animation speed is slower than instant, this makes
resizing windows feel laggy in my opinion. This gets more apparent when
disabling translucency in the desktop effects. I'm not entirely sure whether
this is a bug or expected behavior.
STEPS TO REPRODUCE
1. Set animation speed in system settings to instant
2. Resize a window
3. Set animation speed to medium
4. Resize a window, observe window resize effect lagging behind mouse cursor
OBSERVED RESULT
Window size updates slower when the animation speed is not set to instant.
EXPECTED RESULT
Expected window to update instantly, no matter which animation speed is set.
In case this is expected behavior, is there any way to set animation speed of
specific animations in kwin, so that I could make the windows resize instantly
without setting instant animation speed for all animations?
