Hi, i had the exact same issues, this is because of the nouveau driver. If you disable the driver and properly setup your gpu all these bug will go away. To do that i let you follow a guide i wrote about the install of the nvidia driver. Here is the guide:
NO, apt upgrade on rolling distribution will break the system.
what did this fix for you?
Is it working on AMD gpu?
Probably depends on the model. Have you searched your hw support status on duckduckgo or google?

System upgrade?
apt upgrade
do NOT run apt upgrade parrot is a rolling release you will break your system. you can try to recover but it would be faster to reinstall.
in the future always update with
sudo apt update
sudo apt full-upgrade
OR
sudo parrot-upgrade
I wanted a solution man!
During boot add this line
pci=noacpi
If your pc won’t shutdown .
What do you mean? I thought you said youhave an amd gpu? This is for an intel nvidia. You definitely should avoid adding anything to any boot line
