The dead white pixel appears wherever you are in metro Internet Explorer. It doesn't appear anywhere else in Windows 8.
More info: Sometimes it appears in that position, and sometimes it appears 20px or so lower, so it's not physically a dead pixel. Appears on southparkstudios.com too and other sites with a dark background. Doesn't appear in any other apps so far though. And yes this is Windows 8 RTM downloaded from TechNet.
Even more info: I tried closing IE and opening it again (right clicking it from the side window switcher page and clicking close) and the dead pixel went away. So it definitely seems to be caused by IE. I have two GPU's that I can switch between on my laptop so if it is one of those, I'd be able to switch to another and prove it's not a graphics card driver issue.
It appears to simply be something very random, which is why none of you probably haven't seen it. After closing and opening, it's not appearing right now.
