Bug ID: 511711
Summary: Flatpak apps require being restarted to fully switch
from light to dark, making the new automatic theme
switcher unusable
Classification: Plasma
Product: plasmashell
Version First 6.5.1
Reported In:
Platform: Flatpak
OS: Linux
Status: REPORTED
Severity: normal
Priority: NOR
Component: Day/night schedule

Screenshot of the problem
SUMMARY
Having activated the new auto dark mode feature in Plasma 6.5, when the sun
sets my theme supposedly switches to dark mode. I say ‘supposedly’ because any
flatpak apps which are open at the moment the change occurs need a restart to
make the change effective.
For reference, the attached picture has an instance of Konsole installed as a
system package (right) and an instance of Konsole as a flatpak (left). As you
can see, having changed the theme from dark to light, only the titlebar of the
flatpak konsole has changed colors, while the app itself is still in dark mode,
and will remain so until I close and reopen the window.
This happens with pretty much all Qt apps installed from flatpak, such as
Okular, Gwenview, Kile, etc. Those same apps installed as rpms change themes
perfectly.
This makes the new theme switcher feature unusable in flatpak-reliant systems
(e.g. Kinoite, Bazzite, etc)
STEPS TO REPRODUCE
1. Open a Qt app installed from flatpak
2. Switch to dark theme
3. Observe that the app does not change to dark theme until restarted
OBSERVED RESULT
Apps do not properly switch from dark to light theme
EXPECTED RESULT
Apps should switch themes
SOFTWARE/OS VERSIONS
