massively annoyed with Gtk. Why can't I put box-shadow on loads of things? ListBox: nope. EventBox: nope. TreeView: nope. Entry is fine. And CSS applies to these things; I can set borders and background colours, but if I set a box-shadow, it's just not there. There is no indication of why this is, or anything. I've got plenty of margin room for it to show up in.
