Sigma30mm+LowLight=Focus Issue (newest 0.3firmware installed)

Hi,

I recently bought the Sigma 30mm for my A6300. Today I tested the lowlight capabilities and there was an issue with the autofocus. In AF-C mode, everytime I focused on something /tried wide/zone/flexible spot/ after I started recording, it instatly (or 1-2sec later) dropped the focus and started breathing. Every. Time. Before I pressed REC everything was fine, even if I shake the camera. I might think the reason is because its too dark, but then why it works before I start recording? I mean it doesnt start breathing and the focus is just great on the subject.

AF speed and AF track sens is set to normal.

Update: Oh, and I downloaded the newest firmware (0.3, released 02.23) and still have the problem.
