Well, after a couple of tests, it actually turns out that pfPWinFBConfigAttrs
does not seem to work properly under IRISGL operation. The sample program
/usr/share/Performer/src/pguide/libpf/C/pipewin.c would work OK -as far as FB
config is concerned- under OpenGL/64-bit operation, but not with
IrisGl/32-bit!
I also tried to implement this hint regarding PFFB_DEPTH_SIZE, set to 23
instead of 24, and the results are :
- no effect under IRISGL operation, both depth-size and stencil_bits
are zero,
- with OPENGL, PFFB_DEPTH_SIZE reads 15 (what! is that all?) and
STENCIL_BITS is 1, as expected. Can't we get depth-size to 23, really?
This is very likely to be a problem for all of us who are porting their
applications to full OpenGL, I suppose. Or is it a iR-specific issue ? Is the
problem solved in Performer2.1, maybe?

Gilles Reymond
