[GRASS-dev] Re: GRASS 7 compiled from source on Ubuntu 11.04, error with 3-D view.

[Isaac Ullah]

Actually, now that I am thinking about it, this may be related to an
ongoing NVIZ problem that I have had since moving to Ubuntu 11.03.
Essentially, what happens is that NVIZ only *sort of* works in that I can
get it to load up and display a map, but as soon as i touch any of the
controls with the mouse, the map canvas goes blank. I can see glimpses of
the map in coarse mode as if I rotate the view or zoom perspective or raise
the height, but the display always goes back blank as soon as I stop
moving. Sometimes the display DOES come back if I briefly click the eye
arrow and then don't move the mouse, but this is only temporary. This
happens on all three versions of grass I have installed (6.4.1 from ubuntu
GIS repository, 6.4.2 from SVN snapshot binary, and 7.0 compiled from
source). This is *not* the same exact issue with the 3D map display in 7.0,
which just doesn't even load through, but it *is* an error I have been
having with 3D display of maps in GRASS in general...
