There are issues using Alt+Tab ↹ in fullscreen mode. If used too many times, it will disconnect players connected to your server and can even crash the game.
Unfortunately, Ubisoft's netcode only supports a max of 30 frames per second for proper sync between players in multiplayer. Bypassing this limit results in things such as co-op actions not executing properly, and so on.
Edit: You can download this program from fans called Framer and unlocks the frames on Multiplayer, Download:http://steamcommunity.com/sharedfiles/filedetails/?id=265715221
There is an issue for some users happening at random after a couple of minutes where the game disconnects both players while playing the co-op campaign. The issue can be encountered 100% during the training mission while hacking the first laptop the players come across. In subsequent missions it seems to happen randomly after some time. No real fixes have been reported that work for everyone. For some completely uninstalling NOD32 solved the problem.
