Bug ID: 359531
Summary: [wayland] add support for xdg_shell should stop gtk3
applications from crashing
Product: kwin
Version: 5.5.4
Platform: Fedora RPMs
OS: Linux
Status: UNCONFIRMED
Severity: normal
Priority: NOR
Component: wayland-generic
Assignee: kwin-bugs-n...@kde.org
Reporter: dah5a...@genodeftest.de
Currently, any gtk+ 3.x application (with wayland rendering backend enabled by
default) starting inside kwin+wayland will crash.
Reproducible: Always
Steps to Reproduce:
1. Run a kwin_wayland session, even a nested one works:
$ kwin_wayland --xwayland --windowed
2. Start any gtk3 based application
$ gnome-calculator
Actual Results:
segfault in wl_proxy_marshal_constructor() because the proxy is NULL.
Expected Results:
No crash
According to Oliver Fourdan (RedHat) this is because kwin@wayland doesn't
implement the xdg_shell protocol yet.
I am posting this here so nobody will wonder why gtk+ 3.x applications always
crash on start.
