I'm not encountering any issue, can you show me a screenshot or some footage?
Which version of the game are you playing?
That's very odd. I have not received any reports except this one of this bug and I am not able to reproduce it myself. I'm really not sure what to do about it.
While I can't tell if it would fix it, have you looked into updating your graphic card driver?It could potentially mess up games in general.
