No sure if it's meant to be like that but here goes:
If the thumbnail size is set to more than 120x120 in Settings>Local Settings, then in the member profile page the horizontal scroll bar appears at the bottom as part of the thumbnail doesn't fit the page.
In the 3.5.6 version, the fields in the profile page were moved automatically to accomodate the bigger thumbnail so there was no need for the horizontal scroll bar.
I think that looked better.
