Description ftl1 2025-12-28 08:51:32 UTC 
SUMMARY
Native apps, such as konsole, dolphin and others make everything freeze for a brief time before unfreezing again. Can't move the mouse and can't see anything else update visually whilst it freezes

STEPS TO REPRODUCE
Maximizing almost any window

OBSERVED RESULT
brief freeze on everything 

EXPECTED RESULT
no freeze at all

SOFTWARE/OS VERSIONS
Windows: 
macOS: 
(available in the Info Center app, or by running `kinfo` in a terminal window)
Linux/KDE Plasma: fedora 42
KDE Plasma Version: 6.5.4
KDE Frameworks Version: 6.17.0
Qt Version: 6.9.3

ADDITIONAL INFORMATION
This most likely isn't a downstream issue, since I could also experience it on arch a while ago and I should also maybe mention that it doesn't happen on debian, which probably means it only happens on newer versions of Plasma.
