It looks like there's a fan vs strip type of situation going on here on top of whatever's causing the lines to appear. The first draw with a GS shows the bad behaviour: 813290 @0 glDrawRangeElementsBaseVertex(mode = GL_POINTS, start = 0, end = 24630, count = 24630, type = GL_UNSIGNED_SHORT, indices = 0x15eb10, basevertex = 413659) So it takes points in and outputs a triangle_strip. Perhaps that's where things are going wrong?</pre> </div> <hr> You are receiving this mail because: <ul> <li>You are the QA Contact for the bug.</li> </ul> </body> </html>
