Subject: intel: Use the current context rather than last bound context for a drawable.
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=dea5e57861ec998cb7ee913a8819752cb9fa946b;p=mesa.git

intel: Use the current context rather than last bound context for a drawable.

If another thread bound a context to the drawable then unbound it, the
driContextPriv would end up NULL.

With the previous two fixes, this fixes glx-multithread-makecurrent-2,
despite the issue not being about the multithreaded makecurrent.
