Animation appears with fog

Again I post it, since I got no responses. The problem is simple to describe: the animation of a sprite sheet appears with fog. I’m working at 150 DPI, I’ve never had problems before.

Can you post the image?  You might have not a clear transparency, or something in the upper-left corner of the sprite.
