Wine Enable GTK3 Theming

So in winecfg I have checked the Enable GTK3 Theming box under the staging tab and restarted my system, I don’t know if I am missing something but it has not applied the GTK3 theme that I have set in Plasma System Settings under Application Style > GNOME/GTK Application Style.

Does anyone know how I can fix this. Is there some other things I would need to do to get my windows applications to use GTK3 theme?

Recent wine-staging versions doesn’t work with it, no idea why (probably coz it’s still experimental)…
Some time ago it worked though

You can try this:

Uniform theme and fonts for Qt apps in GTK environments – Discovery (

:wine_glass: :wink:


I tried that and found it had no effect on the theme wine uses on windows application, I actually was going to keep qt5ct until I opened dolphin and noticed it was using some other weird theme.
