Hi,
In testing, the only issue I have had is in dealing with Cover images. When set, they look great, can be repositioned. Navigate away from your profile, go back to it - cover image back to default.
Similar issue for Front page image in settings there. It uploads, it even displays in admin, but does not appear on the front page of the Jomsocial section.
I have not yet tested events, but kinda expect more of the same, TBH 🙂
Interestingly, it works in WAMP (i.e. I took a backup of the live test site, installed it on WAMP, and it works - no tweaking of anything, just a straight Akeeba backup and install)
