Only play Manager Career mode offline (disconnected from EA servers), and have noticed the same glowing green random pixel ball floating around the pitch. For me, generally is only located in the bottom right corner of the television screen, however, I use co-op camera settings. The majority of the time, occurs in certain Premier League matches, rarely appeared in La Liga EA Sports stadiums. Educated guess is a game coding monitoring device or tool utilized during gameplay testing by developers, that was not turned off, before the release of Title Update 4. Very annoying to say the least, and just another item to add to the bug/glitch list of problems arising from the latest update.
