Video of the issue

SUMMARY
Double-click on task manager button at the edge of screen initiates drag&drop. Video of the issue is attached.

STEPS TO REPRODUCE
1. Place cursor over window button on the panel at the right edge of screen
2. Double click on it

OBSERVED RESULT
Drag&drop is initiated and immediately cancelled, window is minimized/unminimized once

EXPECTED RESULT
Window is minimized and then unminimized (or other way around)

SOFTWARE/OS VERSIONS
Linux/KDE Plasma: openSUSE Tumbleweed 20250319
KDE Plasma Version: 6.3.3
KDE Frameworks Version: 6.12.0
Qt Version: 6.8.2

ADDITIONAL INFORMATION
I use Plasma Wayland, with 100% monitor scaling.

When clicking on window button *not* at the edge of the screen (i.e. in the middle of the button) the issue is not present and expected result is observed.

Cannot reproduce the issue on git master.

Does it happen in a new clean user account, with the default panel moved to that screen position?
Comment 2 TraceyC 2025-03-26 17:52:20 UTC
I see what's happening in the video. I also can't reproduce this on git-master
Comment 3 Nate Graham 2025-03-26 17:55:34 UTC
Ok, let's call it fixed in 6.4, then!

Yes, though for some reason the issue only reproducible when panel is on top or to the left. With my current configuration it is present with all four panel positions.

BTW Plasma froze the first time I entered edit mode (I didn't see anything suspicious in logs though).
