I am having the same issue on Nintendo Switch.
I'm not sure this is a duplicate of MC-2067. On my Fedora 19 system, 1.5.2 has no problems with fullscreen, but 1.6.1 gets me behavior described here.
Also note that the behavior is slightly different – in that bug, the pause screen comes up, but here, it doesn't.
