Since Minecraft Bedrock 1.13, there are a lot of camera bugs. For example, the wrong hand position, or clumsy sneaking animation. This report is about the camera tilting bug. In Java and Bedrock 1.12.X, the smooth animation plays when flying up, down and jumping. However, since 1.13, it brokes: the camera tilts "backwards" (tilting up when it should tilt down, etc). In 1.15 beta the tilt brokes completely and applies only on hand or handheld item.

Also, in Java and Bedrock 1.12.X, another animation plays when player walks. The camera shifts depending on the position when previously played walk animation stopped maybe, idk how can I explain this. On 1.13 camera shifts down with the same speed as on 1.13. On 1.14+ it shifts much slower (see MCPE-156072).

UPD. The tilt issue also affects Java 1.14+ version but only for jumping and flying, but it also needs to be fixed.
