--- Comment #16 from poma <pomidorabelisima at gmail.com> ---

Within nv50_exa.c, regardless of the function or statement FALLBACK-ed,
commented or deleted, at best, the effect is the same as with disabling EXA
Composite.

It has a positive effect on Greeter Background image loading,
BUT produce at least corruption of some of the icons within Desktop session.
