Gnome theme all over the place, please help

My gnome is all messed up. The theme is all over the place. Some windows are transparent and dark, for example settings and files. Others just have different themes, like dconf-editor and extension manager.
I feel like I have tried everything. Even a dconf reset -f /org/gnome/ to get back to defaults. But nothing seems to do the trick.

Thinking maybe someone on here will be able to help me? :)

As an aside, and not to get into the whole snap/flatpack whatever deal. My snap-apps have wrong cursor theme, and this seems to be a thing I am supposed to live with or something? Is there a solution to this? :)

Update:

Ah ok. I have finally figured this out myself. It seems that some of these applications are GTK4 apps. Theme settings for these apps are simply a css file in a folder, and not related to any other settings in gnome. Thats pretty silly if you ask me… ~./config/gtk-4.0/gtk.css
