Bug ID: 466530
Summary: Crash when using vokoscreen
Classification: Plasma
Product: kwin
Version: 5.27.1
Platform: Other
OS: Linux
Status: REPORTED
Severity: normal
Priority: NOR
Component: wayland-generic
Assignee: kwin-bugs-n...@kde.org
Reporter: aleix...@kde.org
Target Milestone: ---
Happens 100% reproducible using vokoscreen by selecting the "Area" option and
interacting a bit with the controls it creates.
While it could be that it's not generally well implemented, kwin should not be
crashing.
