Nouveau weirdness with google-chrome

[Tom Horsley]

It is wonderful that the nouveau driver works out of the box
not on my GTX 750 Ti and 4K monitor, but I have just been
noticing a weird thing:

Using google-chrome with the window resized to be a good chunk
of the full 4K screen, when scrolling a page, it looks like
big diagonal chunks of page are scrolling independently till
it all settles down again when I stop scrolling. Or maybe
like a wave is running across the screen.

I don't know if it will get irritating enough to send me
back to nvidia binary drivers or not :-).

Weirdly, it does seem to be isolated to google-chrome.
I just scrolled through the same page on firefox and
didn't see the effect.
