Subject: freedreno/a3xx+a4xx: fix GL_POINTS lockup w/ GLES
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=b24c9a8aeef6fbad06d7982aee8bdb55679289f3;p=mesa.git

freedreno/a3xx+a4xx: fix GL_POINTS lockup w/ GLES

point_size_per_vertex is always TRUE for GLES, causing us to configure
the hw as if gl_PointSize was written, even if it was not.  Which makes
for grumpy hw.
