--- Comment #1 from Daniel Richard G. skunk@iskunk.org 2010-12-01 00:40:57 PST --- For some reason, the blanking does not occur when I run Wings3D in the standard Ubuntu desktop (GNOME + Compiz). I normally use Xfce/Xubuntu, and the bug occurs there, and it also occurs in a minimal X session with twm.
