Yeah this bug used to happen to me a while back and now its affecting my multiplayer servers again! Whenever I join a multiplayer server I get kicked about 30 seconds later, just when every player in the lobby freezes, but I can still move. Pls Help. I think the bug was fixed a week later when it was reopened last time. ;(
And when it is on fullscreen (fn f11) the 'exit','restore down' and 'minimise' do not show up. I'm on 1.8.8
Yay! The bug has fixed itself.... (for me 😛).... after 3 days of boring singleplayer.
