I registered just to say I have the same exact issue and I was really hoping that by the RTM that it'd be ironed out. For me, it's on an Intel Core 2 Duo (1.33GHz) CPU, with GM45 chipset/ GPU.
It doesn't seem to happen with any photos taken on my cell phone, but anything taken with my digital camera has this problem. I also have the problem with 2560x1440 wallpaper that I downloaded off the internet, so it's not just my camera.
