Bug on the new client???

Hello everyone. I opened league today and saw an update on the new client. Downloaded it. It got me to the login screen. I didnt check the box about the keep me signed in. I entered username and password normally. When i entered i saw a picture of a messed up client with nothing but a find game button in the middle. I pressed it, and went into a queue. I closed it immediatelly and reopened the client. I signed in again normally and the old client appeared as i remember it. Did that or something like it happen to anyone else?
