The patch I sent to Bertrand works fine AFAIK.

What are you talking about? The objects render fine. Sometimes a face
clips too soon when it's facing the X axis (I fixed that but haven't
released an update yet). As for distortion have you tried using a PTEX
renderer? I.e POLYTYPE_PTEX_LIT ...etc.

Yes I have seen this problem. It's not my fault, P3D doesn't render
things properly. I would just stick with RENDER_SORT.
The patch I sent to sourceforge is outdated. I sent an updated patch
to Bertrand but haven't heard from him yet.
