Subject: loader/dri3: Don't wait for fence of old buffer when re-allocating it
X-Git-Url: https://git.libre-soc.org/?p=mesa.git;a=commitdiff_plain;h=e34dd4f5084c73c0a2fcadf783e8f7d8199bb5ca;hp=aefac10fecc9ec70feb5923ce3200902f67182ba

loader/dri3: Don't wait for fence of old buffer when re-allocating it

We only need to wait for the fence before drawing to a buffer, not
before reading from it.

This might avoid hangs when re-allocating the fake front buffer, similar
to the previous change. But I haven't seen any evidence that this was
actually happening in practice.
