Question offscreen rendering crashes X server

since 1458 Drivers I've encountered following problem on tnt and gforce cards in connection with amd processor boards:
Every thing is fine including glx running glxgears does not reveal any error.
But when trying to do offscreen renderin from within the TGS version of open inventor the X-server crashes.
It allready crashes when i try to quest the size of offscreen buffer in pixels.
The application loads the nvidia glx as offscreen rendering works with mesa.
It even works under Windows allthough one has to set buffer size empirically als open inventor reports zero size.

For the 1458 version it seemed to work but since than i only got crashes even when turning off agp ...

I've just downloaded the drivers for redhat 8.0.

I've allready tried the hints from the faq's and checked this list for hints ... but didn't find anything apropriate or the hints didn't solve my problem

so what could and should i do be able to use the offscreen rendering from within open inventor without having to use mesa software gl(x)?

XFree log with verbosity level 10 says in the logfile aprox 4000 lines select returned 0 and than server abborts with signal 11.
There are no errors during startup and disabling agp doesn't help.
(still have the logfile. if needed i'll send it)

It is strictly linked to hardware supported offscreen rendering with nvidia >= tnt2 and corresponding drivers.
