Subject: vc4: Don't try to use color load/stores to blit across format changes.
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=b229e6c7dee2bb6b1736d6867790dfcd1c50f623;p=mesa.git

vc4: Don't try to use color load/stores to blit across format changes.

We could potentially support the right combination of 8888 to 565, but the
important thing for now is to not mix up our orderings of 8888.  Fixes
fbo-copyteximage regressions.
