Bug ID: 471275
Summary: Closing laptop lid resets output scale to default and
crashes Firefox
Classification: Plasma
Product: kwin
Version: master
Platform: Other
OS: Linux
Status: REPORTED
Keywords: qt6
Severity: normal
Priority: NOR
Component: wayland-generic
Assignee: kwin-bugs-n...@kde.org
Reporter: n...@kde.org
Target Milestone: ---

Journal log
STEPS TO REPRODUCE
1. Use Plasma 6 Wayland on a laptop
2. Set a scale factor that is not identical to the scale factor that
OutputConfigurationStore::generateConfig() generates as a default value
3. Open Firefox with some tabs
4. Close the lid
5. Wait a moment to make sure it's gone to sleep, and open the lid
OBSERVED RESULT
Screenlocker shows the default scale for your output, not the one you chose.
After unlocking, Firefox freezes and then crashes. Both of things happen
reproducibly, 100% of the time for me. Journalctl log and backtrace attached.
Despite the fact that both things happen every time, it's possible the Firefox
issue is unrelated. If so, I can open a new bug report for it after the scale
issue is fixed or investigated to not be connected.
EXPECTED RESULT
Scale not reset, Firefox doesn't crash.
