zoom/animating bg bug?

[wabo]

ok, when ever I set the zoom for the character, and have an animating background, my character blinks along with the background. He has these weird black lines run through him, and I noticed it only happens when I set the zoom for my character to anything but the default.  Any ideas

What colour depth is your game? I haven't been able to replicate this.

[wabo]

well, the color depth is 24-bit, but I've sinced changed it to 32-bit, same results in both color depths.

Can you upload a game that demonstrates the problem?
