I'm not sure if this has anything to do with the issue in this thread (Restart Safari after each 1P update (when updated with Safari running)?) about updating beta, but the AgileBits Web site has display issues with Safari.
What is strange is the team names and icons are not even evident in Chrome and Firefox.
One other minor issue with this site and Safari. Dropping the image on the box to upload, disappears when dragging file to box. Will report to Apple.
