hi, I''m struggling against a strange problem with pbuffers. My pbuffer used with RGBA or Z is polluted by some kind of empty dash-dot lines (??!!) I mean i fill my pbuffer with a Z or RGBA, and Some pixels are not filled and remain empty. don''t understand why !? If I switch to use a framebuffer (or zbuffer) instead of pbuffer, the problem disapear. here''s a picture (hope it works) blue is the clear color, other is my pbuffer partially filled.
