How to fix random freezes on Pop OS 22.04

I've been experiencing random screen freezes on Pop OS, where the mouse pointer can still be moved onto another screen, but one of my monitors is totally unresponsive. I tried a whole range of things to fix this (disabling high DPI, turning off extensions etc), but none of this worked.

In order to fix this, I had to disable hybrid graphics. This is an option when you have both a dedicated GPU and a integrated GPU, generally you want to use the low power integrated GPU when you're using battery. However, something is breaking this on the current version of Gnome on Pop. To disable hybrid graphics:

1. Click on the system tray

import time
import rtmidi

# initialise midi in class
midi_in = rtmidi.MidiIn()

# connect to a device
midi_in.open_port(3)

# get midi msgs
