Really weird color issues, looks like hardware fail

Anyone seen anything like this? It’s from a project I’m currently working on.

See that green-ish tint at the top? It’s not supposed to be there. This screenshot is from a current MacBook pro running latest Flash Player. Topmost in this image is supposed to be a video with an alpha channel and the brown background is supposed to overlap slightly and take over where the movie ends.

Looks like faulty YUV decoding or something.
