Bug ID: 488174
Summary: Moving panel from left screen edge to bottom screen
edge fails and crashes plasmashell in
PlasmaQuick::ContainmentView::formFactorChanged()
after you close edit mode
Classification: Plasma
Product: plasmashell
Version: git-stable-Plasma/6.1
Platform: Other
OS: Linux
Status: REPORTED
Keywords: regression
Severity: crash
Priority: NOR
Component: Panel
Assignee: plasma-b...@kde.org
Reporter: n...@kde.org
CC: niccolo.venera...@gmail.com
Target Milestone: 1.0
Everything built from git master against Qt 6.6.3.
STEPS TO REPRODUCE
1. Have panel on the left screen edge. If it's not already there, move it there
and then restart plasmashell for good measure.
2. Right-click on panel > Show Panel Configuration.
3. Click on "Position" button to expose the arrows pointing at screen edges.
4. Click on the arrow for for bottom screen edge, or hit the Down arrow on the
keyboard.
OBSERVED RESULT
The panel fails to move to the bottom screen edge. If I click the "Exit Edit
Mode" button, plasmashell immediately crashes. This is all 100% reproducible
for me.
