The dark system theme I have set seems to make some applications look funny, with dark boxes where they should be light. Is there any way I can manually set a theme on a per-application basis?
This is a common but solvable problem. I'm afk so can't link the right pages, but look up the LibreOffice and/or consistent gtk/qt theming entries on Arch Wiki
Edit: https://wiki.archlinux.org/title/LibreOffice#Theme might be useful. It also links to https://wiki.archlinux.org/title/Uniform_look_for_Qt_and_GTK_applications, which is worth looking into as well
