Rekordbox issue

Every time I open Rekordbox, pieces of the software (Cue buttons, play button etc) are missing until I hover over them with my cursor. A lot of other things will stay completely hidden, making the software impossible to use. I have looked everywhere online but I cannot seem to find the solution, was wondering if anyone else has ever had the same issue, or whether it may be an issue with my PC?

I've attached some images so you get an idea of what I'm talking about as it's quite hard to describe. Any help would be great, thanks!
