to execute

$ sudo hcitool lecup --handle 3585 --latency 0 --min 6 --max 8

  [HP ZBook Studio G5, Ubuntu 18.04.3 LTS, bluetooth mouse] Choppy/laggy
  bluetooth mouse cursor movement

Status in xorg package in Ubuntu:

Bug description:
  1. Pair Logitech MX Master 3 bluetooth mouse with Ubuntu 18.04.3 LTS (don't 
use Logitech bluetooth dongle, use built in laptop bluetooth)
  2. Move cursor.
  Cursor movement is choppy, laggy, like it's having 20 FPS refresh rate.

  execute in terminal: `sudo hcitool lecup --handle 3585 --latency 0 --min 6 
--max 8`
  This command must be used every time the mouse is connected to the laptop 
(after turning on the laptop, after some time of mouse inactivity etc.).

  When using Logitech bluetooth dongle this problem never occurs.
