Bug ID: 500519
Summary: KWin crashes when bogus size window is created
Classification: Plasma
Product: kwin
Version: 6.3.1
Platform: Arch Linux
OS: Linux
Status: REPORTED
Severity: crash
Priority: NOR
Component: generic-crash
Assignee: kwin-bugs-n...@kde.org
Reporter: w...@nereid.pl
Target Milestone: ---
I have not initialized a variable in my wayland client program, which resulted
in a request to create a nonsense size window. Instead of refusing the request,
KWin crashed.
