there's a lot more corruption going on than just a few artefacts
around buttons - see https://bugs.webkit.org/show_bug.cgi?id=25696
for more details but basically scrolling with mouse or keyboard
_completely_ trashes the screen, with artefacts appearing in
blue or black or from random memory areas.
this is something of a showstopper for an embedded app project
so if you or anyone else have any clues as to what needs to be
done, fixing this, that would be great.
paul if you have some patches already that would be great.
