--- Comment #12 from Gert Wollny <gw.fossdev at gmail.com> ---
I might add that the DIV is lowered in glsl to RCP+MUL before it is translated
to TGSI, so no need for it there. 

When I look at the bicubic shader with the offending opcodes, I have to say
that using DIV there is a bit lazy, because the DIVs act on constants or
uniforms or combinations of these, and it would probably be better to pass them
reciprocal value in (I just don't know (yet) where the constants are actually
passed in to change this).

Anyway, since there is already a CAP for TEX_LZ I was able to create a simple
fix:
