I switched to Cinnamon instead of i3 for a while, and recently I've been having trouble with some Cinnamon/GTK themes. I like Cinnamon, but the theming support is horrendus.
My problem is that when I use some GTK themes, the padding and buttons around some menus and options are missing, and highlighting text can be weird at times (although for some reason, this isn't a consistent problem). I know some CSS, so I don't have a problem editing the GTK's CSS files, I'm just not sure what tags I need to edit.
The themes that I run across this problem with are (so far) Arc, Mint-Y (based on Arc, built for Cinnamon, strange that it doesn't work), FlatStudio, and Windows 10 Light from Gnome-look.org.
The default Adiwata theme and the Maia themes that come with Manjaro work, and Paper almost works except it has a white line on the left side of my screen.
Screenshots:
Notice here, using Adiwata, that the buttons at the top are normal looking.
Now look at those same buttons using Mint-Y, they are just text, with no padding and no actual button shape or highlighting
Here, using the Arc theme, the items in the contet menu have no padding, no structure, and the items that expand have no arrows, nor do the options that should have checkboxes have checkboxes.
Here, using the Maia theme, the options look totally normal, and all the icons and such are in the correct places.
Any tips would be appreciated. Just one thing I thought I should mention, this is only a problem when I change the Controls option in the menu, but is unaffected by the Window Borders, Icon theme, or Desktop theme. This shouldn't really be a problem, but this option apparently changes the entire GTK theme.
