Bug ID: 458059
Summary: Kwin abort
Product: kwin
Version: 5.24.4
Platform: Kubuntu Packages
OS: Linux
Status: REPORTED
Severity: normal
Priority: NOR
Component: core
Assignee: [email protected]
Reporter: [email protected]
Target Milestone: ---
SUMMARY
KWin keeps crashing on my platform with signal 6. (stack below), this happens
like 0 to 5 times a day. I noticed nothing particular about the activities at
the time of the crash. For me it's usually while using chrome, but this is what
I usually use.
I noticed one more thing related to the compositor, hope this helps. If the
system is newly turned on I can observe tearing in chrome while scrolling. My
settings: scale: smooth, latency: "prefer smoother animations", vsync:
automatic. If I change latency to whatever tearing goes away, but bringing back
the previous setting does not cause tearing. Looks like jiggling settings
always helps.
