hm, that's strange. Can you set the environment variable OSG_LOG_LEVEL
to the value DEBUG, run the tutorial 29 and send me (since it might be
large, please send it to me directly carsten_neumann AT gmx DOT net) the
output, please ?

There have been some changes to the FBOViewport since 1.8.0 was

don't mind trying a more recent version (i.e. CVS snapshot), maybe it
solves the problem, although I still would like to understand what is
going wrong.
