My MacBook started having this weird graphical issue when I upgraded my bootcamp partition to windows 8.1, and I've tried updating the graphics driver, among other things and nothing seems to fix it. I downgraded to windows 8 to see if that would fix it, and it seems to have fixed it.

Here is a video of the issue: http://youtu.be/6ICiCFfWv8I

On another hand, every once in a while when I resume the laptop in Mavericks I get a weird, kinda similar glitch that looks like this:

This issue never happened under mountain lion, and it only happens when I resume the laptop from sleep, it never appears once the laptop is already resumed successfully.

I've tried resetting both the PRAM and the SMC, and neither seem to fix either of the issues. Does anyone have any ideas that I could try to fix the windows 8.1 or mavericks issues? Or might this be a hardware problem?

Thanks!
