[Bug 89034] Firefox crashing xserver and some major rendering bugs

--- Comment #37 from Tom Stellard <tstellar at gmail.com> ---
After examining the shader dumps one thing that looks suspicious to me is that
in the good dump, we have several instructions like this:

image_load v[9:12], 15, 0, 0, 0, 0, 0, 0, 0, v[4:7], s[8:15]

But nothing is ever written to the last component of vaddr: v7

However, in the bad dumps we have:

image_load v[8:11], 15, 0, 0, 0, 0, 0, 0, 0, v[1:4], s[8:15]

And a value is stored in the last component of vaddr: v4 before every image
load.
