After some time playing, it appears at rondom, my HUD buttons start flickering between the connected xbox pad (used for playing the game) and the M&K keyboard controls for no visible reason.
I also disconnected the mouse once, to check if it has an effect, but it didnt. Flickering was still in place and will only be gone if I quit the game entirely and restart it.

Has anyone experienced this bug and a solution?
Because it is damn annoying.
