Please attach the corresponding Xorg.0.log and output of glxinfo.

It's hard to believe that commit causing the problem; it shouldn't make any
functional difference.

true. that's the "last working" commit. a commit after that breaks things. ok,

--- Comment #8 from vebveb@hotmail.fr ---
I had the same issue (bug 77602), and disabling forcing si_dma_copy to always
go to the fallback solves the tiling issues and the glitches.

I have a CAPE VERDE card (hd7730m).

We may need a similar fix for async dma as we did for displays.  See bug 71488.

The async dma code is probably setting the band size incorrectly on these
asics.

--- Comment #12 from vebveb@hotmail.fr ---
I have tested to force to go to the fallback only before calling
si_dma_copy_tile,
to test if si_dma_copy_buffer was working.

I didn't notice any glitch or tiling problem with heaven, but I don't know if
si_dma_copy_buffer is actually used or not.

I have tested to return V_009910_ADDR_SURF_16_BANK
in case 8 in si_num_banks, instead of V_009910_ADDR_SURF_8_BANK,
and unigine have no glitches anymore.
