Bug ID: 482704
Summary: auto-hide non-floating bottom panel hides despite
mouse cursor being at the edge of the screen
Classification: Plasma
Product: plasmashell
Version: 6.0.1
Platform: Other
OS: Linux
Status: REPORTED
Severity: normal
Priority: NOR
Component: Panel
Assignee: plasma-b...@kde.org
Reporter: bastimeyer...@gmail.com
CC: niccolo.venera...@gmail.com
Target Milestone: 1.0
SUMMARY
This started happening after the upgrade to Plasma 6.
The panel incorrectly hides itself in certain situations while set to auto-hide
and non-floating, despite the mouse cursor being at the edge of the screen
where the panel is attached to. This seems to depend on the panel height, so
this must be caused by some kind of faulty fractional offset calculation or so.
When moving the mouse cursor towards the edge of the screen, the panel
correctly gets shown, but if the cursor is then moved away a bit while still
hovering the panel and the cursor then touches the edge of the screen again
without further mouse movements, the panel hides itself again, which is bad. I
could only observe this faulty behavior while using certain panel sizes. I am
using the default breeze (dark) theme, in case that matters.
STEPS TO REPRODUCE
1. Have a panel with the following properties:
- bottom
- center
- full width
- auto-hide
- translucent
- non-floating
- height 42 (or 38)
2. Have no windows open on the desktop
3. Move the mouse cursor towards the bottom edge of the screen -> panel appears
✓
4. Move the mouse cursor up a bit while still hovering the panel -> panel stays
✓
5. Move the mouse cursor towards the bottom edge again and keep it still ->
panel hides ✕
When the panel size is set to 40 for example, this issue does not occur
