Bug ID: 463612
Summary: Electron apps hang GUI when run with Wayland backend
Classification: Plasma
Product: kwin
Version: 5.26.4
Platform: Archlinux
OS: Linux
Status: REPORTED
Severity: crash
Priority: NOR
Component: wayland-generic
Assignee: kwin-bugs-n...@kde.org
Reporter: ivdo...@gmail.com
Target Milestone: ---
SUMMARY
GUI becomes completely unersponsive as soon as any Electron-based application,
such as Slack or Atom is run with --ozone-platform=wayland. Any headless
processes still work, e.g. nginx, KDE Connect and Docker workloads, but
terminating session with kquitapp5 plasmashell; kstart5 plasmashell doesn't do
anything.
P.S. I KNOW THAT BACKTRACE FILE IS EMPTY. I can't do anything after triggering
this hang, including syncing GDB state to disk.
STEPS TO REPRODUCE
Run %app% --ozone-platform=wayland &
OBSERVED RESULT
GUI becomes completely unersponsive as soon as any Electron-based application,
such as Slack or Atom is run with --ozone-platform=wayland. Any headless
processes still work, e.g. nginx, KDE Connect and Docker workloads, but
terminating session with kquitapp5 plasmashell; kstart5 plasmashell doesn't do
anything.
EXPECTED RESULT
No freezes, app uses wayland backend and fractional scaling
