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?
I mean the boxes for font and paragraph style are all dark when they should be light. I think it's got to do with the system theme, I just wish I could selectively choose the theme for each application so dark mode doesn't mess things up like this.
By default I have the same issue using KDE and a dark theme, what I do is set a specific theme inside LibreOffice. Another thing you can look for is setting another GTK theme or color scheme inside Customization on Plasma Settings
