Bug ID: 389231
Summary: kwin_wayland crashes when opening kscreen KCM
Product: kwin
Version: git master
Platform: openSUSE RPMs
OS: Linux
Status: UNCONFIRMED
Severity: crash
Priority: NOR
Component: wayland-generic
Assignee: kwin-bugs-n...@kde.org
Reporter: fab...@ritter-vogt.de
Target Milestone: ---
Flags: Wayland+
When the kscreen kcm on wayland gets closed (by closing systemsettings or
switching to a different module), systemsettings5 dies with a wayland protocol
error.
When instead of closing the kcm you go back and open the kcm again (sometimes
multiple attempts are necessary), the whole session dies as kwin_wayland
crashes.
