Bug ID: 484199
Summary: KWin fails to start with KWIN_COMPOSE=O2ES on X11
Classification: Plasma
Product: kwin
Version: 6.0.1
Platform: Arch Linux
OS: Linux
Status: REPORTED
Severity: normal
Priority: NOR
Component: compositing
Assignee: kwin-bugs-n...@kde.org
Reporter: ballog...@gmail.com
Target Milestone: ---
SUMMARY
If I set the KWIN_COMPOSE=O2ES environment variable, and I try to login to the
Plasma (X11) session, kwin fails to start, and a desktop session is started
without a running window manager. The Wayland session works with this
environment variable, only the X11 session fails.
STEPS TO REPRODUCE
1. Set KWIN_COMPOSE=O2ES environment variable in /etc/environment, then
restart.
2. Start Plasma (X11) session.
3. See that the window manager is missing.
