Description Nate Graham 2024-06-07 18:43:41 UTC 
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.

EXPECTED RESULT
The panel moves to the bottom screen edge without drama

How I reproduce the issue

I'm attaching a screen recording that shows me reproducing the issue so you can be sure you're testing the same way.
Comment 3 Nate Graham 2024-06-10 15:18:06 UTC 
It's also not CatWalk causing it; I removed that widget and the problem still reproduces.
Comment 4 Akseli Lahtinen 2024-06-14 11:07:15 UTC 
I managed to reproduce it!

I had to make sure the panel alignment is not center, but its left.

I think when its moving the panel, the alignment changing might be causing the crash.
Comment 5 Akseli Lahtinen 2024-06-14 11:13:40 UTC 
Adding my backtrace too for good measure
