problematic mouse sensitivity since the update to 1.16.200

why since the update to 1.16.200, the mouse movement is a bit paused and delayed, I've set my mouse sensivitas to low sensivitas, but why still pause and delay, I've tried in minecraft java and it's fine no problem, before the update to 1.16.200 (1.16.100) My mouse sensitivity is not a problem either...
