12-40mm & GX8 AF Weirdness

Strange problem.

Traveling for the first time since the lockdowns and was taking some shots in a museum courtyard, overcast sky.

The lens snapped into focus, but when I hit the shutter button it instantly lost focus and the shot was blurry. I did 3 or 4 more shots with the same problem. I checked the snap-back focus ring and it was OK. Tried a manual focus shot and it was OK.

I think this happened on another day, but didn’t notice the mis-focused shots until my nightly review.

It’s really odd. Anyone see this before? Could it be the IBIS? I’m stumped.

Mis-focus.
