Flaring & Vignetting issues of 17-40mm f4L on Full Frame DSLR?

[Canonised]

Hi Everyone!
I would like to know how many of those who own a FF DSLR and a 17-40f4L suffered some levels of unhappy flaring and vignetting.

ALSO - if so, are there ways to work around it? Do other lenses fare better?

Thanks!
Regards
