Subject: vc4: Disable RCL blitting when scissors are enabled.
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=d16d666776ee12659145f08bd35566dd2cc0f925;p=mesa.git

vc4: Disable RCL blitting when scissors are enabled.

We could potentially handle scissored blits when they're tile aligned, but
it doesn't seem worth it.  If you're doing a scissored blit, you're
probably a testcase.

Fixes piglit's fbo-scissor-blit fbo
