Its happening on all the systems we've tested at the iX office. Various
nvidia cards, Intel i5 / i7 chipsets. On the laptop I tested here it is
running an ATI radeon 5400 series, i5 Proc. When this occurs, I don't
see any particular messages in dmesg or Xorg.0.log that would indicate
the problem. We've tried it with 3D enabled and disabled to try and rule
that out.
