That's strange, I haven't seen that before. Unfortunately the graphics engine is supplied by Godot, the game engine I'm using. I have no control over it, so I'm afraid there's not much I can do there :( Could also be a driver issue maybe?
Its possible! I tried reinstalling twice and nothing seemed to fix it. Tried messing with different graphics options, FPS, ect ect. I'll look into it more and see if maybe it's something with Godot.
