Actually this checkerbox rendering thingy is already implemented in some newer version of current SGS1 firmware. I am personally using it now so i can attest to that. Only certain version though. Basically, when u pinch to zoom, everything will be blurred as u pinch, and it will only refocus the text/image once u release your finger. Sure, the advantage is that it's a lot smoother, but it's also less pretty to eyes

. The original browser on older firmware, will refocus the text real time as you zoom, and this will cause sluggishness if the website is graphic/flash heavy, but it's also more pleasing to the eye as you can read while you zoom. So, there's a compromise to both, unless the phone is powerful enough to refocus real time as you zoom.
However,"stop-rendering" during zoom pinching is a completely separate thing if i'm not wrong. I don't think SGS1 has that feature.
"stop rendering" is just my guess because checkerboard in the world of graphics design means transparency, something like a space of void that allows background images to be visible. Makes sense as my guess would be the zoom process actually involves the phone taking a screenshot of the page, resize it based on finger movement and then render the webpage based on zoom level.
The reason I wanna identify the rendering method is coz i wanna find a browser that has that implementation, and compare both rendering methods. Pretty sure the Sensation will not have that rendering style.
Unless, the whole thing is actually due to hardware acceleration (which I've read from youtube comments).
Anyway, by 'refocus' you mean the text become blur? Or 'text reflow'?
