Anyone got a green flicker issue on P7P?

Hi this started yesterday.

Only my standby/always-on screen flickers green like this, any ideas or do I need to to send it in for a replacement?

Nothing new downloaded, nothing installed, just sat on my desk for some calls.

Edit: When locking my phone all CPU cores seem to get maxed out based on a cpu monitor app.

Edit 2: I contacted Google support and after i confirm if my warrenty is valid for google or my phone provider ill exchange it for a new one.
Also the flicker exclusively appears during always on mode.
