Created attachment 127911 [details] mixed_themes SUMMARY If I run out of disk space, newly launched applications will use the default KDE theme, icons, and colors instead of the ones I have configured, while already-opened windows retain the configured theme/icons/color, save for the titlebar and the space for rounding corners at the bottom. After freeing space, new apps still keep launching with the default theme/icons/color until the session is restarted. STEPS TO REPRODUCE 1. Set oxygen theme, oxygen icons, and some dark color scheme. 2. Fill all disk space. 3. Launch some app. OBSERVED RESULT Apps should launch with configured theme, icons, and colors. EXPECTED RESULT Apps launch with the default (breeze) theme, icons, and colors. SOFTWARE/OS VERSIONS Linux/KDE Plasma: (available in About System) KDE Plasma Version: 5.17.5 KDE Frameworks Version: 5.62.0 Qt Version: 5.12.5 ADDITIONAL INFORMATION Attached a screenshot with an instance of Dolphin which was launched before running out of space and another which was launched after.
Seems like you shouldn't be filling up your disk entirely. :)
This bug is different from the linked bug as this not about plasma startup, but about what happens after plasma is already running and the disk becomes full.
