If you have ever had the text of the game (any text, from crit hit, #s, and kills) stick to your screen, I might have found a way to get it to leave the screen... when the text starts stayin in place, go buy a small, or large potion of HP, I have done this around 3 times (not much) and the text is gone.
This is just for the players, the Devs are aware of the bug, so this is for the players so they can fix it as of now, with no update or fixes implemented... I THINK IT WILL WORK, NOT 110% SURE....
