Hi Martin,

Would it be possible for you to try another machine?  A none ATI
one... ATI OpenGL drivers don't have a great history for stability and
quality, especially under Linux.  The errors in the screen shot
suggests an OpenGL bug to me.

As to why a CVS update might trigger such a bug is next to impossible
to say without doing a lot of testing to isloate things.  It might
simply be a slight difference in OpenGL state (even valid stat), or
perhaps have configuration of objects in memory might be enough to
trigger the error.

One thing to look for is output of error messsages to the console - by
default the OSG checks once every frame for OpenGL errors and if finds
out it reports it, and ups the granularity that it checks for errors.
If the OSG is sending erroneous OpenGL data then typically you'll get
message printout out to the console.   OpenGL does catch all problems
though so the OSG can still send invalid pointers etc, but in general
the OSG should play nice and send everything along safey.  The OSG is
used by a great number of users so such problems tend to get spotted
and fixed pretty early on in a features life.

This occurs On FreeBSD-5.3/i386 with XOrg-6.9 DRI drivers on an ATI
Radeon9200 as well as on Linux/AMD64 (Debian Etch) with XOrg-7.1 (I
guess) and ATI's commercial display drivers.

I did numerous CVS updates (up and down) and recompiles of the whole
OSG source tree, so errors were unlikely to occur here.
I'll see if I manage to nail the rendering error down to a single file,
I just can't spend the whole day on it ....

        Martin.
