The store window has a nasty "noise/moire" (or is it some kind of resampling?) effect that renders text near-unreadable at certain spots. f you resize the window (tho the content itself is not resized), this noise/moire effect moves about in patterns over the whole html rendering surface, clearing up some parts and messing up others instead.
There's also a diagonal "tear" across the whole window from top/left to bottom/right.
These (well, the tear anyway) were also present on test, so I'm kind of surprised no one noticed them before release...
