Description necessarypaint 2024-03-09 21:15:02 UTC

SUMMARY
After setting a window decoration other than breeze and oxygen, attempting to minimize an application with the mouse (using a keyboard shortcut works fine) will cause some plasma functionalities that require clicking to break. This includes window buttons of applications, selecting applications from overview and the 3d cube. By continuously clicking the maximize or close button of any application, the window will maximize/close successfully and the bug fixes itself until trying to minimize something again.

STEPS TO REPRODUCE
1. Set a window decoration other than breeze and oxygen
2. Minimize a window with the mouse

OBSERVED RESULT
The application minimizes, and attempting to use plasma functionalities that require clicking such as the ones mentioned earlier will not function properly

EXPECTED RESULT
The application should minimize without any issue whatsoever

SOFTWARE/OS VERSIONS
Linux: Arch Linux
KDE Plasma Version: 6.0.1
KDE Frameworks Version: 6.0.0
Qt Version: 6.6.2

ADDITIONAL INFORMATION
I have attached a video that shows the bug being in action

Another thing I would like to mention is that sometimes continuously pressing the maximize/close button will not fix the bug either and you will have to switch between applications until you find one that randomly functions

Can reproduce this bug.
changed window decoration to "Plastik" after some clicks  buttons doesnt react anymore to mouse, Cube doesnt work, Screen Edge Overview shows but nothing clickable there.

Comment 4 rodolfosilva2 2024-03-13 10:28:48 UTC

maybe has something in common with https://bugs.kde.org/show_bug.cgi?id=480864 
and https://bugreports.qt.io/browse/QTBUG-121987

only happens to me when changing window decoration to other one than the standard breeze,.

Comment 5 rodolfosilva2 2024-06-21 04:01:50 UTC

i just upgraded to Plasma 6.1.0 on arch.
The misplaced context menu issue https://bugs.kde.org/show_bug.cgi?id=480864 is resolved.

But this issue persists. Upon changing Window decoration to eg Plastik the minimize, maximize, close buttons don't react anymore.
Also Cube does not spin as described in #1 post.

Please investigate further.
