Bug ID: 419595
Summary: 6abd23ed0220b14a4a05fa280869ba3c953565e3 makes KWin
crash in KWin::Cursor::pos()
Product: kwin
Version: git master
Platform: Compiled Sources
OS: Linux
Status: REPORTED
Severity: crash
Priority: NOR
Component: general
Assignee: kwin-bugs-n...@kde.org
Reporter: n...@kde.org
Target Milestone: ---
Created attachment 127242
--> https://bugs.kde.org/attachment.cgi?id=127242&action=edit
Full backtrace
With everything built from source,
https://cgit.kde.org/kwin.git/commit/?id=6abd23ed0220b14a4a05fa280869ba3c953565e3
causes KWin to reproducibly crash on launch for me. A full backtrace is
attached, and the relevant bits are included below. If I revert that commit, it
stops crashing. As it happens, I did a clean build of the entire KDE software
stack this morning, so it's not an issue of an outdated build directory
somewhere in the stack.
