I've also seen these happening a lot in the generated videos,
I don't know for sure, But I guess.

This issue could be due to a lot of reasons.

Could be due to:

• landmarks positions on the face not optimal.
• Could be improved due to lil more Fine Tuning.
• retraining of model some examples that focus on lot of closely view/snaps of faces.

Could be any thing The issue is kinda generic, according to me.
