GTK4 apps don’t follow Breeze theme

Help
1

The issues has been discussed here for Firefox. I have the same issue with other GTK4 applications, f.e.

$  pactree -r gtk4
gtk4
├─bottles
├─gtksourceview5
│ └─bottles
├─libadwaita
│ ├─pamac-gtk
│ │ ├─manjaro-application-utility
│ │ │ └─manjaro-hello
│ │ └─pamac-tray-icon-plasma
├─pamac-gtk

Manjaro is recommending to switch back to GTK3. Are there any plans to adjust GTK4 in near future or what would you recommend? It’s irritating. to have all windows in light colors and only the once shown above in black …
Thank you!

The Breeze GTK theme does support GTK 4 apps in general, but not the ones using the libadwaita styling. It’s possible that it could in the future, but this hasn’t been done yet because the GNOME folks have made it hard, and libadwaita is yet another moving target we would have to keep on top of.

@michaKDE, there is a way to get GTK4 applications (packaged via your distribution’s format and installed via its package manager, so not via snap or flatpak) to adhere to the GTK4 theme:

I believe that Arch hosts the original – aur.archlinux.org/packages/libadwaita-without-adwaita-git, but a counterpart exists for for Fedora too (albeit in COPR):

I saw someone try to get it into NixOS, but IDK whether that was accepted:

An anecdote exists that it works on Manjaro:

GNOME and libadwaita is such a disgrace, I wish there would be a universal Working Group whose only job would be porting all those apps to Qt.

@rockandstone, the developers who create applications in GTK for GNOME choose to do so. Despite the apparent reductions in its usefulness to end users, the amount published every 6 months doesn’t appear to be reducing, and most new releases are high-quality, too. There must be something about Qt that is undesirable to them.

Regardless, in effect, KDE is that working group.
