I too am having the same issue with my 360 LCD screen. The first few times open the software would fix it, but now it has grown worse, I'd say probably 45% of the screen is freaking out. However it doesn't seem to grow worse as the PC is on, occasionally appears to self-heal, then revert back to the issue. I can't tell if this is a hardware or a software issue, but given I'm encountering a forum thread about this problem, I take it isn't rare. I'll try rotating my orientation of the screen to see if the problem follows the orientation of the screen or if it follows the orientation of the image.
Edit: It does not follow image orientation.
Second Edit: Update, the glitched portion of the screen DOES rotate (rotates orientation of the gif within the glitched section). If I could get a tech to respond to this thread, that would be awesome. I'm now under the suspicion that the issue is a software issue and not a hardware issue. I'd love to see some attempts to see if it is and to see if a software update could be a fix rather than having to completely disassemble my build to RMA a screen that isn't actually broken. #### if it is the screen and if I could replace the screen without pulling the whole cooler, that would be even better.
