gnome-shell windows sometimes all black

[Scott Doty]

Sometimes, new windows open in gnome-shell show up as
tastefully-rendered black rectangles.  Sometimes shrinking one of these
windows fixes the problem, but it's pretty annoying.

I didn't find anything with a precursory check of bugzilla.  Was just
about to file a bug, but wondered if anyone else had seen this behavior?

p.s. technical info for the curious:

This is on an HP Pavilion tx2000, using the nvidia binary blob driver.
