Not that it's of much consolation, but the nv30 GL driver suck=
s. There are a
number of unhandled situations, and I wouldn't be overly surprised if glamor
were to hit one or several of them.

A "big hammer" approach to fixing some of the issues is running w=
ith
NV30_SWTNL=3D1, although there's plenty more issues that this won't have an
effect on. That usually fixes "bad geometry" issues, however the =
screenshot
seems to suggest that perhaps incompatible color and depth buffers are being
mixed - we print a warning about those in debug builds.

I'll have a look at the apitrace later to see if can try reproducing on my
NV34, although it's possible that won't work this time.
