Bug ID: 455507
Summary: Overview effect search box almost always causes hard
system lockup
Product: kwin
Version: 5.25.0
Platform: Other
OS: Linux
Status: REPORTED
Severity: normal
Priority: NOR
Component: effects-overview
Assignee: kwin-bugs-n...@kde.org
Reporter: indecisiveautoma...@gmail.com
Target Milestone: ---
SUMMARY
Using the search bar in the Overview effect will almost always cause a full
system lockup, requiring me to press the restart button on my PC. It will
either do it the first time I attempt to type anything, or after two or three
times. It will always happen but it seems to happen at latest on the third time
entering any text. The display I attempt to search on seems to have no effect.
Audio from opened applications will continue to play but the system freezes and
the audio cannot be paused, and the desktop cannot be interacted with in any
way. Keyboard shortcuts don't work either. It is a full lockup save for any
audio continuing to play.
I tested with a few applications open and with no applications opened, and the
issue was present in every case. I could not narrow down the issue to anything
more specific than simply searching with the Overview effect. I am not sure
what kinds of logs I should try to find/create/attach but please let me know
what I can provide to help 🙂
Interestingly, this does not happen with KRunner. Only with the Overview
effect.
STEPS TO REPRODUCE
1. Activate the Overview effect
2. Attempt to search in the search box
3. Repeat two or three times if necessary to get the system to lock up
OBSERVED RESULT
Overview effect search bar causes system to lock up, the number of search
attempts to cause this varies but the maximum I have observed is three times.
EXPECTED RESULT
Overview effect search bar should not cause a system lockup.
