[Mesa-dev] [Bug 96853] gl_PrimitiveID is zero when rendering points of size > 1

https://bugs.freedesktop.org/show_bug.cgi?id=96853 --- Comment #6 from Ilia Mirkin --- On a quick scan of the logic, the main issue I noticed was that using the emulated point sprites depends on info->mode (via u_reduced_prim), but instead it should depend on the output

https://bugs.freedesktop.org/show_bug.cgi?id=96853 --- Comment #5 from denis.fisse...@tu-dortmund.de --- (In reply to Roland Scheidegger from comment #3) > In theory if there already is a user-provided gs (which doesn't output > points) then the emulation code doesn't really apply. But I don't

https://bugs.freedesktop.org/show_bug.cgi?id=96853 --- Comment #1 from Roland Scheidegger --- I think this would be a bug in the emulation code used for large points. Specifically, a gs is used to generate two tris out of a point, which means the prim id cannot be first used
