Whenever I run my game in flash player mode, everything works fine, but when I try it in HTML5 a weird black box appears at the top of the screen a few seconds after the game starts, and slowly expands downwards until it covers the entire center of the screen. I am not sure where to look to solve this problem, I have lots of spots where the problem could be coming from - I have a 2 behaviors on every scene that show how many enemies you have killed at the top of the screen and show the title card respectively, I believe the title card one is built-in while the other one is made by me. Those are the only two that use drawing in my game, which I assume is where the problem is coming from.
