Platform: Manjaro
OS: Linux
Status: REPORTED
Severity: normal
Priority: NOR

Switching focus from one window to another causes severe stuttering for a
second or so before going back to normal (this effect is not present when
there's only a single window open).
STEPS TO REPRODUCE
1. activate slide back animation in window behaviour to see this better
2. click off window or on another window to take focus away to display the
animation or alternatively whilst in focus grab a off-focus window and
immediately drag it around the screen
OBSERVED RESULT
stuttering
EXPECTED RESULT
smooth transition
