This was on KDE. On Gnome it still isn't applying the theme.

So, you fixed the qt6 apps (great thanks !), but the qt5 apps sill never had
the adwaita theme applied (on gnome qt5 apps have a greyish-greeny theme).

What about that ?

(and on X11 Gnome hidpi (4k) the qt6 and qt5 scaling is completely different.
Is there anything you can do about this ?

By default qt6 scaling was fine, but qt5 was too big (when using 150% font
scaling in Gnome).

I was able to fix the qt5 scaling by adding these to /etc/environment
> export QT_AUTO_SCREEN_SCALE_FACTOR=0 
> export QT_SCREEN_SCALE_FACTORS=1.5 
> export QT_SCALE_FACTOR=1

But now the qt6 mkvtoolnix has the same problem qt5 apps had before.

So, either qt5 scaling works or qt6, but not both together.

Ayn idea how to fix this ?

Thanks.
