Description John Schroeder 2025-04-17 19:04:38 UTC

SUMMARY
When using the Breeze Dark theme, if a GTK application is started right after logging into KDE Plasma, the GTK application won't have the dark theme applied.

STEPS TO REPRODUCE
1. Set theme to Breeze Dark.
2. Login to KDE Plasma.
3. Open a GTK application (or have a GTK application set to auto start).

OBSERVED RESULT
The GTK application has a light theme (instead of dark theme) applied.

EXPECTED RESULT
The GTK application should have the dark theme applied.

Comment 1 John Schroeder 2025-05-06 16:55:27 UTC

This was fixed in an update to KDE Neon Testing today. KDE Frameworks Version changed from 6.14.0 to 6.15.0 so maybe that fixed it.
