Subject: draw/gs: fix up current verts in output fetching.
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=99ae39f76c90403b7bdc19349275f70df4c57443;p=mesa.git

draw/gs: fix up current verts in output fetching.

This was wrong since I added multi-stream support in
draw/gs: track emitted prims + verts per stream
