Bug ID: 436317
Summary: Compositor broken after waking from suspend
Product: kwin
Version: 5.21.4
Platform: Neon Packages
OS: Linux
Status: REPORTED
Severity: minor
Priority: NOR
Component: compositing
Assignee: kwin-bugs-n...@kde.org
Reporter: boven...@bovender.de
Target Milestone: ---
SUMMARY
When I wake my laptop with KDE neon from suspend-to-RAM, compositing is often
broken. I can get it working again without having to reboot by changing any
compositor-related settings (but it is a bit cumbersome to do so almost every
time I open the laptop).
STEPS TO REPRODUCE
1. Suspend laptop.
2. Wake up laptop.
OBSERVED RESULT
No compositing (i.e., no desktop effects, no 3D).
EXPECTED RESULT
Compositing should work as it did before suspending to RAM.
