Bug ID: 488603
Summary: Screen freezes with compositor enabled
Classification: Plasma
Product: kwin
Version: 6.0.5
Platform: Manjaro
OS: Linux
Status: REPORTED
Severity: normal
Priority: NOR
Component: compositing
Assignee: kwin-bugs-n...@kde.org
Reporter: rocking...@proton.me
Target Milestone: ---
SUMMARY
After updating to Plasma 6 the screen sometimes freezes for ~10 seconds when
trying to interact with the Desktop.
After disabling the compositor the issue doesn't happen.
STEPS TO REPRODUCE
1. Interact with Plasma Desktop, e.g. click on the item in the system tray.
OBSERVED RESULT
The whole desktop becomes unresponsive, only the mouse pointer is functional.
The reaction to the mouse clicks and the keyboard presses during the freeze
only happens after the feeze is over (seems like all inputs are registered).
EXPECTED RESULT
Desktop doesn't freeze.
