FX3 / a7siii 85mm zoom in / focus breathing glitch ?

Hello,

I encountered a disturbing and repeating problem filing on my FX3 with 85mm 1.8 native sony lens.

using wide AF area and touch tracking, with focus sensitivity and speed settings low (each at 3), there is still a repeated phenomenon which looks like an instant push zoom of several pixels, which then pulls back out a few moments later. From looking closely it appears that the zoom is just focus breathing, but it isn't clear to me where focus is being pulled to/from... it occurs in moments where i can't imaging i was changing the focus selection, and even if i was this behavior would be alarming.

Anyone seen anything like this before or have a solution?

Thanks
