Ok, so I flashed the latest mozilla-central on the flame and I am unable to reproduce what is shown on the video. However, sometimes I get incorrect content (wrong parts of the page) rendered in the low-res area when zooming out by a lot (but not every time, it seems to happen only when I have been messing up with the zoom for a long while).

I'll keep looking into this zooming business and hope that the issue you are experiencing is somewhat related.
