EOS Rp + Sigma 50mm f/1.4 Art - strong backfocus on frame corners

Hello,

I wanted to buy Sigma 50 f/1.4 for my Canon EOS Rp. So I rented it to check if everything will be OK. During test shoot I've notices that there are many portrait photos where nearest eye is not in focus. So I've checked the autofocus on the text.

And it works really strange. I thought that mirrorless cameras should focus properly always, but with this lens it always focus slightly back.

On this video I first focused manually, then on 00:00:12 half-pressed shutter button to use AF - and it got out of focus!
