--- Comment #1 from Neil Roberts <n...@linux.intel.com> ---
It looks like in GL 4.4 they have completely removed the restriction that MSAA
resolve blits need to have the same format. In the section entitled “Changes in
the released Specification of July 22, 2013” it says:

“Relax BlitFramebuffer in section 18.3.1 so that format conversion can take
place during multisample blits, since drivers already allow this and some
apps depend on it.”

Maybe we should just entirely remove the restriction in Mesa too. On the Intel
driver the multisample resolve is implemented as a shader so I don't think
allowing all format conversions would cause any problems.
