Bug ID: 399302
Summary: Random OpenGL freeze causes KWin to disable
compositing
Product: kwin
Version: 5.13.5
Platform: Archlinux Packages
OS: Linux
Status: REPORTED
Severity: normal
Priority: NOR
Component: compositing
Assignee: kwin-bugs-n...@kde.org
Reporter: davide.nicol...@gmail.com
Target Milestone: ---
Created attachment 115362

"journalctl -p 2 -b" output
SUMMARY
Sometimes at boot kwin_x11 throws "Freeze in OpenGL initialization detected"
and disables compositing (with OpenGL x.y compositing enabled in
systemsettings). This happens apparently in a random fashion. I am using the
default user configuration files in /home. I put the journalctl log in the
attachment. This error never happened to me before, but I can't recall which
change triggered the error. I recently updated Plasma, though. Clicking
"Re-enable OpenGL compositing" in systemsettings and relaunching kwin
effectively re-enables compositing.
STEPS TO REPRODUCE
1. Enable OpenGL (whatever version) compositing under System Settings >
Composer
2. Restart
3. Launch a Plasma X11 session in sddm
OBSERVED RESULT
No compositing, sometimes kwin_x11 doesn't even start.
EXPECTED RESULT
Compositing working
SOFTWARE VERSIONS
(available in About System)
KDE Plasma Version: 5.13.5
KDE Frameworks Version: 5.50.0
Qt Version: 5.11.2
ADDITIONAL INFORMATION
I am using up-to-date Arch Linux, kernel version 4.18.10-arch1-1-ARCH, 64 bit,
xorg intel drivers version 2.99.917 and mesa 18.2.1-1
