I'm currently using Gnome PopOS 19.10 on a fairly recent machine Acer Swift 3 SF315-41-R03D, and I've been using Linux for around a year.
After I had a clean install of PopOS, I updated everything and then installed Gnome Tweaks. I couldn't but notice that almost all of my applications don't match any theme I choose (even not even Adwaita). I'm talking about VLC,LibreOffice, GIMP, Flameshot and others programs I know should support GTK (and/or Qt). Is there any package I'm missing?

Custom themes worked on Manjaro Gnome on the programs i quoted before and it feels weird they don't work here
