2012 21.5" iMac wake from sleep white screen probs

I have my new 2012 21.5" iMac. It's a top end one with fusion drive for ref. when I'm waking it from sleep I get a total white screen, with the time in digital in the top RH corner, and nothing.

First few times I had to hold down the power button to restart it. This time I shook the mouse and had the effect whereby it "colours/reveals" the screen when I move about, pixel by pixel if you understand?

By doing this I was able to see my login n,ae, clicked this and the screen went to my password ask screen, which was fine.

Bit worried on this as its a brand spanning new iMac. Is it just me or is my iMac (already) faulty? I'm sure I had it a few times on my old 2007 Alu iMac as well.

Any help?
