Bug ID: 488916
Summary: Panel hint scaling or transition errors
Classification: Plasma
Product: kwin
Version: 6.1.0

OS: Linux
Status: REPORTED
Severity: minor

Mentioned persistent scaling/presentation error on the application menu
SUMMARY
A "hint" in the following is referring to the dialogue which appears when
hovering over widgets or icons on the panel, I am unaware of the formal name
for this object.
Quickly moving between widgets, the icons in the icon task manager, or the
application launcher immediately as the hint dialogue is shown can cause odd or
incorrect scaling behavior. Outright errors in scaling similar to the images
attached below happen significantly more frequently between widgets, or icons
in the task manager which have different hint types (name vs showing window).
I expect this is being caused by some form of interpolation between new hints
being composited, as the Application Launcher screenshot in particular is
something you can briefly see in the transition between it and the system
settings.
STEPS TO REPRODUCE
1. Hover cursor over widget which shows some variety of hint.
2. Quickly move mouse between multiple types of hints
3. Observe scaling issues
4. (Optional) Quickly move between the application menu and the first icon on
the task manager before stopping on the application menu to reproduce
scaling/presentation error.
OBSERVED RESULT
Incorrect presentation of hints if moving between hints of dislike type
EXPECTED RESULT
Hints of dislike type should present and scale correctly between each other,
even if this means delaying presentation (i.e. the user stops erratic mouse
movement)
