Bug ID: 452634
Summary: KDE Overview Effect is laggy until any Windows is
dragged to left/top/right
Product: kwin
Version: 5.24.4
Platform: Ubuntu Packages
OS: Linux
Status: REPORTED
Severity: normal
Priority: NOR
Component: effects-overview
Assignee: kwin-bugs-n...@kde.org
Reporter: sort...@gmail.com
Target Milestone: ---
SUMMARY
***
The overview effect is laggy. After the animation for drag to top edge, left,
right is launched, the overview effect starts to work really smooth!
***
STEPS TO REPRODUCE
1. Login to KDE
2. Launch Overview Effect
3. Open any application and drag the window to any part (just the animation is
required, even the "dragged" action does not need to be completed)
OBSERVED RESULT
Just starting, the overview effect seems laggy, as if the FPS is lower than in
the other effects or animations (I am using 144 Hz screens). Once I dragged a
window to the left, right, or top and the animation of the black shadow is
launched, the overview effect stops being laggy and starts to work as smooth as
the other effects/animations.
This is happening on my desktop with 144hz screens and Nvidia Drivers
570.60.02.
EXPECTED RESULT
The Overview effect should be as smooth as the other effects or animations,
without any trick.
