The most but not all without is2D? As you see in the sources, this flag
only uses GL2PS_SIMPLE_SORT instead of GL2PS_BSP_SORT.

It's difficult for me to find the cause for your problem without beeing
able to reproduce it...

Can you call glFlush () in gl2ps-renderer.cc in a for loop together with
some wait function? Just to be sure it isn't a timing problem where your
graphics-card-driver doesn't flush it's output buffers. Btw, have you
tried to update your GPU drivers?

Another thing I would test: can you remove GL2PS_OCCLUSION_CULL and
inspect the eps if the lines are mssing or only hidden by some other
primitives?
