Description Olivier Bilodeau 2025-12-12 04:50:07 UTC
SUMMARY

In the last org.keepassxc.KeePassXC update 2.7.11 they updated to the KDE platform org.kde.Platform/x86_64/5.15-25.08 and since then window decorations are no longer following the Adwaita theme I have installed and forced.

STEPS TO REPRODUCE
1. Install org.keepassxc.KeePassXC on a Gnome desktop in dark mode
2. Open it
3. Witness the Window decoration

OBSERVED RESULT

Non Adwaita, non dark, KDE/QT looking theme

EXPECTED RESULT

Adwaita theme that follows the desktop preference of light or dark
