Small beta client bug

Hey there. I recently updated the beta client during the newest patch. I thought it seemed laggy so I immediately closed and reopened the client after updating. When I logged in the client began rescanning all of the files. It displayed it's progress over where the play button should have been. It was odd that it let me log all the way in. Then it closed the client and updated itself again. Afterwords I was brought to the login screen. No big deal really but I'm sure it's something you guys want to look at. Also I get a lot of images showing through the lobby screens. I didn't remember the specifics of that bug for you guys though.
