Subject: glx: fix glXQueryContext(GLX_RENDER_TYPE)
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=521e4b9b7e3c79e7362f7cbd594a2e8cf74cdfe4;p=mesa.git

glx: fix glXQueryContext(GLX_RENDER_TYPE)

The renderType parameter to CreateContext() was never used.  Also, it
was often passed as zero.  Now when it's zero we check if the context
is RGBA or CI mode and set it accordingly.

Fixes bug 24211.
