my DE is Gnome
Ah, so are you using Kvantum, Qt5/Qt6 Settings (qt5ct) or Gnome Platform for Qt applications? It might be related to your /etc/environment … This should help:
GNOME is setup by default to use QGnomePlatform and Kvantum. Qt5 Config can also be used with Kvantum, but only one Platform Theme can be used at a time.
Edit your /etc/environment for system-wide changes or ~/.profile for user account changes.
# For Qt5 Config, use qt5ct
QT_QPA_PLATFORMTHEME="gnome"
QT_STYLE_OVERRIDE="kvantum"
I saved the options I’ve come across. I haven’t been able to find documentation, either.
QT_QPA_PLATFORMTHEME
Available options: gtk2, gnome, kde, qt5ct, xcb
QT_STYLE_OVERRIDE
Available styles: HighContrastInverse, HighContrast, Adwaita-HighContrastInverse, Adwaita-HighContrast, Adwaita-Dark, Adwaita, kvantum-dark, kvantum, qt5ct-style, Windows, Fusion
The packages are still in the repos, they’re just not used by default for the GNOME ISO profile anymore.
It works for me and everyone …
