Hello,
I am using Windows 8.1 with Windows Media Center. I have my display resolution set to 1920x1080p with 59.97Hz refresh and the same setting in Media Center. Whenever I exit Media Center and go back into Windows, I see severe graphic distortion and glitching (see this video for example nuc error.mp4 - Google Drive). I thought this was a refresh rate issue so I tried 60Hz and still have the same issues. I've updated my BIOS and graphics drivers to the latest version. Any ideas how to fix this issue? The only way I can get around it is to reboot the machine.
