Commen= t # 13 on bug 91808<= /a> from Dave Airlie 
Just adding some things I've tried to fix this to no avail.

use RECIP_FF/CLAMPED instead of RECIP_IEEE
use RECIPSQRT_FF/CLAMPED instead of RECIPSQRT_IEEE
use MUL/MULADD/DOT4 instead of IEEE

Split constants into DOT4, rewrote DOT4 output to go via another register.

Disable scaled 16-bit float vertices, this change the misrendering to somet=
hing
worse for some reason.

I've noticed the broken drawing operations are the same vbo/ib with a diffe=
rent
set of constant values for VS constants 124-126, the first draw works and d=
raws
the inside gear, the second draw to draw the outside gear fails.

I considered then it might be constant caching or vertex caching since we u=
se
vfetch to fetch the consts, tried add more flushing between draws, tried us=
ing
uncached descriptor for constant buffer.

Nothing above has fixed it, merely logging it for my own sanity at this poi=
nt.
