Bug ID: 446454
Summary: kwin_wayland crashes on simpledrm with an egl client
Product: kwin
Version: git master
Platform: Compiled Sources
OS: Linux
Status: REPORTED
Severity: crash
Priority: NOR
Component: compositing
Assignee: kwin-bugs-n...@kde.org
Reporter: bluescreenaven...@gmail.com
Target Milestone: ---
Hi
I actually think this is probably something to do with commit
737074d368bcf5aa3a388908f1776261d46dbb8b in kwayland-server
If I start kwin (drm) with
kwin_wayland weston-simple-shm
(it's on simpledrm)
kwin does not crash
If I start it with
kwin_wayland weston-simple-egl
kwin crashes
This is on simpledrm, but I think QXL too.
If I export LIBGL_ALWAYS_SOFTWARE=1, this is a workaround
Below is the relevant stack trace I get:
