I can't fix this by myself, because I don't have your GPU. If you want to play
with it, here's how:
In mesa/src/gallium/drivers/r300, there is file r300_texture_desc.c. On lines
356 and 357, there are two arrays containing info how HiZ buffers should be
aligned:
static unsigned hiz_align_x[4] = {8, 32, 48, 32};
static unsigned hiz_align_y[4] = {8, 8, 8, 32};
The 3rd element in those arrays contains a number for your GPU (because your
GPU has 3 pipes). Currently the alignment is 48x8. Feel free to try a different
size, like 32x32, 64x64, 48x32, whatever comes to your mind.
If nothing helps, it means the alignment is right and the problem is somewhere
else.
