I'm somewhat surprised Mesa doesn't expose any of ANGLE/EXT/NV in GLES2 contexts. If it did so - and if etnaviv actually implemented instanced rendering, which it definitely has code to sometimes do - then I suspect you wouldn't need this patch. > The problem is that etnaviv offers GLSL 140 on GL 2.1 and glamor > rendering assumes that glVertexAttribDivisor() is always available on > GLSL>=130, which is not the case here.

Regardless, this is better than it was. Merged, thanks: remote: I: patch #223110 updated using rev 7437b6dbdee050f8ebb3a79b9077d051c91880c3. remote: I: 1 patch(es) updated to state Accepted.
