In Minecraft: Java Edition, the distance your in-game cursor moves depends on the speed at which you move your mouse. In Bedrock Edition, moving your mouse a certain distance always results in the same cursor movement, no matter how fast you're moving it.

This results in having to move your mouse more overall, there being less fine tune control, and gameplay feeling inconsistent between the two versions.
