Bug ID: 466357
Summary: Flickering in systray for apps that change tooltip or
on mouse hover
Classification: Frameworks and Libraries
Product: frameworks-plasma
Version: 5.103.0
Platform: unspecified
OS: Linux
Status: REPORTED
Severity: normal
Priority: NOR
Component: libplasma
Assignee: plasma-b...@kde.org
Reporter: k...@fuchsnet.ch
CC: m...@ratijas.tk, notm...@gmail.com
Target Milestone: ---
Created attachment 156678
--> https://bugs.kde.org/attachment.cgi?id=156678&action=edit
screencast of the issue, first half is app only with no user interaction,
second half is mouse hover
SUMMARY
The flickering in https://bugs.kde.org/show_bug.cgi?id=463685 /
https://bugs.kde.org/show_bug.cgi?id=463061 is still present, new bug report
because it's not specific to qbittorrrent (even though that's a good candidate
to trigger it) and the others are closed.
STEPS TO REPRODUCE
1. Have an icon in the systray that changes its tooltip
2. Alternatively mouse-hover an icon such as volume
OBSERVED RESULT
Heavy flickering, which (especially when not caused by mouse hover but rather
by the app itself) causes the eyes to focus there as there is movement
EXPECTED RESULT
No flickering

ADDITIONAL INFORMATION
Introduced by

Not fixed yet by

The question if this is caused by an animation to fade-in / -out is if that
animation is really needed as is.
Because if it is mainly / just for aesthetics, this most certainly does the
opposite of what it tries to achieve.
Also: is it needed for the icon to reload / do that whenever the tooltip
changes? If not, disabling that would at least fix it for the case where there
is no user interaction, which would be a good start
