GTK4?

[cryptoquick]

For some reason, in one of the more recent version of GNOME, I can't pick this as a modern theme, it's only for legacy applications, so things like GNOME System Monitor display in the fugly Adwaita theme instead of the sleek, retrofuturistic stylings of this blackout theme. Is there anything that can be done for compatibility with newer apps?

What distro are you on? It may be because the system monitor app is installed as a flatpak

I'm using Arch. It came installed with gnome using pacman.

You can try these commands and see if it works

While I have flatpak installed, I tried running flatpak run --command=bash org.gnome.Calculator, and got this:
error: app/org.gnome.Calculator/x86_64/master not installed
I do have Calculator installed, so I'm guessing that Arch installed it without using Flatpak
After running flatpak list, it's completely empty.
I don't think this is a flatpak issue. If I had to guess, maybe something changed in GTK4 that leaves apps like Calculator and System Monitor unaffected by user styles somehow? Maybe it has to do with dark mode. Not sure.

I think those apps may use libadwaita. I currently don't know how to change themes for apps using that library

Good thinking. I looked into it a bit, and I was able to use this hack to get it to work on some apps:

Also, there was no gtk4 folder, only gtk3, but it seemed to work fine when I just renamed it.

So far it works on Calculator and Disk Usage Analyzer, but it looks really ugly:

It does not work, however, on System Monitor or Nautilus, like it used to.

well, at least some parts work 🙃

will see what happens next, probably another rewrite, or a rebase on adwaita/yaru

I'd be super grateful! The Adwaita design is super fugly to me 😹
