Default [Q] Screen messed up after screen turns on

Hi guys,

I have a GT-P7310 and was running ICS for a while. Decided to give CM10.2 a spin but got the following results:

I thought, bad rom and I put the latest KK nameless, but same thing! Now I went back to ICS and the problem still persists!

It happens only when I reboot, let the screen go off and then turn the screen on with the power button. Have to reboot by pressing the power button for a while.

Touch etc works fine, just the screen.

What could be the problem here?
