Whenever I am playing the game my character just randomly looks away without me doing it.
Seems to be related to CPU charge. Limiting framerate & video settings limit occurency.
When game opened to LAN, other players are affected too.
Something related to MCPE-35910
I can confirm the issue in 1.14.3, also running on Linux.
When I connect an external monitor an watch a stream at the same time, it is much worse. If I just run minecraft it is better.
I experienced this before 1.14.3 already, but it got worse with 1.14.3.
Also in 1.14.3 it is not looking away randomly anymore, but looking the direction I last faced when I opened my inventory.
