Summary: Glitchy, flickering artifacts while rendering tooltips
on system tray and certain applications
Classification: Plasma
Product: kwin
Version: 5.25.5
Platform: Compiled Sources
OS: Linux
Status: REPORTED
Severity: major
Priority: NOR
Component: compositing

SUMMARY
With the Plasma system tray and certain applications like LibreOffice, if one
drags the mouse cursor across multiple UI elements that displays a tooltip,
there is a chance that certain tooltips will leave a badly scaled and
flickering tooltip (shadow?). These glitching, flickering artifacts is often
scaled quite large and will not disappear unless another tooltip overlapped it,
or that region of the window is redrawn.
For a better illustration of what I described above, please refer to this Imgur
post (attachment size limit).
