okay, so i have tried what you wrote, up to the point of Aero theme. im lost. i just recently noticed my background is doing this, and i am a VERY OCD person and i'm getting pissed off about it. i have a custom slideshow and it used to transition perfectly, and now it just snaps to it. i read the top and can not figure out for the life of me how to make my slideshow aero and i read the Red warning. still lost..
