What on earth is going on.
So, whenever I do stuff in LMMS and it shows a popup, some really weird stuff happens.

Whenever I open a popup for opening a file or whatever, it gets all weird and layers stuff on top of itself, and makes a trail with my cursor. Buttons don't even show up until I hover over them. This isn't what it looks like for me, I have no clue why It's transparent in the screenshot. And this happens to the main window too whenever I try to drag carla into the song editor. What is going on?
