Checker board screen

[sopanella]

Does anyone notice a blue and white checker board appear when tapping on the screen or mpving it? It happens when I surf the web. Is this normal?

I'm getting a black and white one. Black lines with white squares this happens when a website is loading or I switch between sites. The blue and white boarder was distracting enough. But this checker board is worse. Now I don't know if that wifi update had something to do with it, but that's when I started seeing it.
It's almost like there is not enough memory and that shows up prior to the page loading.
