b33r, your inability to reproduce the bug is expected. This problem seems to occur only with Nvidia 8xxx (8-series) cards, and only for users of the proprietary drivers.
As a side note, I have successfully used the fix proposed by Nick B. (I don't know what libwfb does - or should do - but creating the symlink to the Xorg version apparently works with no side effects, so this might indeed be a packaging issue.)
