Glitchy looking background and video

Hey, Have been using Kodi with my amazon firestick for a while, no probs at all. decided to install it on my pc, and it all works fine except for these graphical glitches all over the place. ive tried googling the problem but its kinda difficult to describe so i keep getting lead down the wrong route to a solution

Any help would be very much appreciated! Thanks
