I went through (2) copies of this lens and had focus shift in artificial light that made very soft images. I have used the 35L and other fast primes previously on the same body and never have seen shifting like that. For whatever reason, it did not play nice with me and I returned both of them.
After that, I have seriously have had four or five people PM me and tell me they have the same issue, what to do, etc...
My focus did not shift with distance at all with either copy... Both were flawless with 0 MA on my 5D3 in normal lighting near and far. Indoors, it front focused and required +10 to be sharp. Was annoying to switch all the time.
It is quite common of an issue though. But people who don't shoot in the mixed lighting a lot may never have an issue or notice it. But since I use this lens equally indoors/outdoors, I noticed it VERY quickly. Became a hassle. Used (2) 35L's prior and never had any issue indoors, even though I *know* phase AF does change a bit with different lighting. The Sigma showed it a TON more. Too bad, though... The IQ is insane.
I think I will just wait and pay double or whatever it will be for the 35L II when and if it comes out... Spoiled by the Sigma IQ now compared to the 35L, but want reliable AF in any lighting condition... I may try once more in a few months with the Sigma from Amazon, so I can easily send it back if it still has the same issue.
