Fullscreen problem.
 

When I go to fullscreen mode, another color is read as transparent, aside from the color I specified. It is 0,0,0. So when I go fullscreen, the state I use doesn't show properly. Anyone know what is wrong?

Never use true black. Use 19,19,19 (Graal Black). It's a weird thing that cropped up a lot more with gifs.

Better yet, use hex #010101

It's exactly the same as #000000 (true black), but it doesn't get read as transparent.

This is an old Graal thing :)
