Hello:

Thanks for the advices. The problem is partially solved.
First let me state what I have changed
        i) I am using double buffering, this is checked
            from the visualID for my pfPipeWindow
        ii) I am using immediate draw mode.
            This is done by calling
                setDrawMode(PFGS_COMPILE_GL, PF_OFF)
                  setDrawMode(PFGS_DRAW_GLOBJ, PF_ON)
            for each geoset
        iii) I am running the program on a IR, Onyx II
             two pipes machine. Each pipe renders
             two channels
        iv) Set the initial iseg mask to 0 (since I
             am not doing any intersection right now)
             by calling:
        grotto_obj->root[i]->setTravMask(PFTRAV_ISECT, 0x0,
                                       PFTRAV_SELF|PFTRAV_DESCEND,
                                           PF_SET);
         v) update the bounding box whenever the geoset geometry
           changes. This is done by:
           gset->setBound((pfBox*)NULL, PFBOUND_DYNAMIC);

After all these changes, image on my master channel is fine for the
most part, and the image on the other channels are still flashing.
And I notice the flashing only happen when my geoset has more than
one primitives.

Thanks for any advice.

Ed.
