I played most of my playtime on 3.7-8, as recommended by another user, and ignored things not displaying properly in the launcher since the game seemed to work fine. Finally tried 7.0-4 recently, and it's night and day. Launcher works perfectly and had a couple options I was just thinking I'd prefer, I didn't even realize the menu tips were supposed to scroll through, and several more things weren't quite displaying properly in-game and now look so much better.

Never, ever take someone's advice on here without first checking to see if you have the same issues. (And please report your distro, thank you!)
