Bug ID: 486900
Summary: Low FPS/laggy rendering of floating panel adjustment
when switching virtual desktops
Classification: Plasma
Product: kwin
Version: 6.0.4
Platform: Fedora RPMs
OS: Linux
Status: REPORTED
Severity: normal
Priority: NOR
Component: effects-various
Assignee: kwin-bugs-n...@kde.org
Reporter: waynejw...@outlook.com
Target Milestone: ---
STEPS TO REPRODUCE
1. Have a floating panel.
2. Have a maximized window on virtual desktop #1.
2. Do not have a maximized windows on virtual desktop #2.
3. Switch between the virtual desktops.
OBSERVED RESULT
The animation of the adjustment of the floating panel (to either expand to the
edges/borders or retract from them) is rendered with very low FPS which looks
laggy.
EXPECTED RESULT
A smooth animation.
