SUMMARY
***
NOTE: If you are reporting a crash, please try to attach a backtrace with debug symbols.
See https://community.kde.org/Guidelines_and_HOWTOs/Debugging/How_to_create_useful_crash_reports
***
Some shortcuts (like layout switching) trigger without waiting for last shortcut key release. Example: ctl shift shortcut is triggered without shift being released. After that, this key will be eaten, and some bigger shortcuts, like ctl + shift + arrow won't work and ctl + arrow shortcut will be triggered instead

STEPS TO REPRODUCE
1. Set main shortcut for layout switching to "shift + alt"  
2.  Try to disable compositor using "shift + alt + f12" shortcut

OBSERVED RESULT
Compositor will be disabled

EXPECTED RESULT
Compositor won't be disabled and (custom) "shift f12" shortcut will be triggered

This is known upstream issue https://gitlab.freedesktop.org/xorg/xserver/-/issues/258. In particular, the shortcut assigned through main shortcut is handled by xkb.

Alternatively, if you set the shortcut in Alternative Shortcut, it will use kglobalacceld's modifier-only shortcuts, which trigger on release instead of press.
