At this point, I'm working on the internal user experience of my site when it loads. I already got things better by making DOM elements hidden while changes are being applied to them, whilst being careful not to modify the adsense DIV box on my site.

My question is, would blanking out the entire webpage window for 200ms (including blanking the adsense ad unit) violate adsense policies?
By blanking, I mean clearing the contents of the screen.
