Bug ID: 442910
Summary: Tooltips for table cells flicker when moving mouse
slowly
Product: kwin
Version: 5.22.5
Platform: Manjaro
OS: Linux
Status: REPORTED
Severity: normal
Priority: NOR
Component: general
Assignee: kwin-bugs-n...@kde.org
Reporter: tuberculinise_ce...@aleeas.com
Target Milestone: ---
SUMMARY
After a tooltip for a table cell is shown, slowly moving the mouse inside them
causes the tooltip to flicker. A workaround is to disable the Morphing Popups
desktop effect (found in this issue:
https://bugs.kde.org/show_bug.cgi?id=416531).
STEPS TO REPRODUCE
Either:
1. Open KSysGuard
Or:
1. Open System Settings
1a. Select the Systemd section
2. Hover over a table cell until its tooltip appears
3. Move the mouse quickly inside the row and notice that the tooltip does not
flicker and only changes position when the mouse stops moving
4. Move the mouse slowly inside the row
5. Move the mouse one row downwards (or a column over for KSysGuard) and repeat
steps 3 and 4
OBSERVED RESULT
When moving the mouse inside the first row slowly, the tooltip follows the
mouse closely and quickly appears and disappears.
When moving the mouse inside the second row (or column for KSysGuard) slowly,
the tooltip follows the mouse closely but may either flicker or have its text
flicker with the text of the previously-shown tooltip; the font size will be
scaled up or down so that the size of the tooltip does not change.
EXPECTED RESULT
The tooltips do not flicker and their text contents remain constant while
inside a single table cell
