Dear Performers

I use a Onyx2/IR 2RM with IRIX 6.5.5 / Performer 2.2.6, framebufer size
1024x2304 (3x 1024x768).
The visual selected by pfuChooseFBConfig has normally 23 bit depth.
When I load my OpenFlight terrain database, I see a flickering (Z-fighting)
of the coplanar polygons (ex: at the
roadborder). The database has been loaded with the pfdCombineLayer option.
When I configure the pipe window in a way, that I get only 15 bit depth, the
flickering disappears.

Does anybody know this effect ?

Shouldn't it be better with 23 bit than 15 bit depth buffer size?

Thanks for any help

Hans-Peter
