I haven't tested this yet, might do that later. The idea behind the gestures however is to use them all the time, not turn them off. I`ve no idea if this is a MIUI bug, otherwise the EU time could fix the 'bug' that requires it to be turned off in certain situations (which defeats the purpose of having the gestures in the first place).Try disabling full screen gestures. Worked for me.
It seems that Android detects them as an overlay, so in some cases user input is disabled as a protection.
