This is not good at all. The post is definitely sloppy within the frame.is
Of course I have no idea whether the post is below spec. or the frame over.
I can't tell from the photo, but if the seat tube uses an insert, it's an easy fix with a new insert. OTOH - if the post is supposed to fit without an insert it's more serious.
Assuming the post is on spec (measure to confirm) I could consider the frame unacceptable.
FWIW have you considered the possibility that you're using the wrong size post and the right size is 0.2mm larger?
