We'll have to come up with a proper implementation for GL_PRIMITIVES_GENERATED in the multiple streams case. It looks like none of the counters work in all cases. We may need to use atomics in the geometry shader to count things manually for streams 1-3, and hack stream 0 to use CL_INVOCATIONS_COUNT unless a GS program that uses streams is active, then use atomics, and add both sources together to get the final value. Ugly, but I can't think of anything better...</pre> </div> <hr> You are receiving this mail because: <ul> <li>You are the QA Contact for the bug.</li> </ul> </body> </html>
