Focus peaking not accurate with long lenses?

I have a Panasonic GX-7.

I received my Minolta/Sony Alpha to m4/3rds adapter today. So I decided to try my Minolta 100-300 zoom, with the adapter it became a 600mm at the long end.

When focusing on a street light, both the pole and the light were in focus according to the "Peaking". But normally that isn't so with a 600mm lens. Also tried it on the outside "Cat", tried to focus on the eyes but always the Peaking lit up on the whole head.

There's no way to get accurate focus unless I turn off the Peaking feature.

Also when setting the Stabilizer for Legacy lenses do I use the actual focal length or double it. So do I use 300mm or 600mm?
