I found this thread that seems to address the issue:
It is a regression in Qt 6.8.2, reported and fixed in 6.8.3 with requests to backport the fix to distros
My system:
Operating System: Manjaro Linux
KDE Plasma Version: 6.3.5
KDE Frameworks Version: 6.13.0
Qt Version: 6.9.0
Kernel Version: 6.6.90-1-MANJARO (64-bit)
Graphics Platform: X11
How to solve this?
