Subject: st/mesa: flush bitmap cache on query and conditional render boundaries
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=4f4855b249cbcb77900e9767041becf255afbba1;p=mesa.git

st/mesa: flush bitmap cache on query and conditional render boundaries

Bitmap caching shouldn't affect the results of the queries and
conditional render.

NOTE: This is a candidate for the 7.11 branch.
