Hello,
If this patch is acceptable by everybody then
I guess that we need to push the following mesa patch before this one
to avoid errors from Intel CI because the fix for an issue which is tested
by this test is still there.

One of the last comment from Kenneth Graunke <kenneth at whitecape.org>:
