xrandr freezes mouse pointer in script

Hello there,
I am using Xubuntu 16.04. I have a script that sleeps and asks xrandr for monitors connected in a loop. My problem is that this script, each time it runs xrandr, freezes my mouse pointer... This does not happen when running the command manually. This is a minimal example:

Code:

#!/bin/bash



while true

do

  sleep 4



  xrandr | grep " connected" | wc -l

done

Above script returns amount of monitors connected. When I turn it on, each time xrandr is called mouse cursor freezes for a while. What could be the case of this? Also, maybe there is a better way of finding out how many monitors are connected? Maybe a file watcher? But which file?

I would appreciate all help and hints regarding this.

Code:

#!/bin/bash



while true

do

  sleep 4

  ShootME=$(  xrandr | grep " connected" | wc -l )

  echo "$ShootME"

done
