Looks like only snow is wrong? Curious, I will fix it but it may be hard as it looks ok on most computers.
I see what you mean. To me it initialy looked like continious white blinking blobs and tended to be distracting (as though it wasn't meant to be so striking) - sorry about that - I should have looked at it more closely. I immediatly thought it was a pixalation problem that I thought wasn't there before the upgrade. Again, sorry for my over-reaction.
But it definitely is a real problem and should be fixed, is it even blinking?
