This script broke my machine

[EuphoriaCelestial]

I found this repo in the process of trying to use my android smartphone as second screen. This worked fine, I am able to create a virtual monitor and teamview to it from my smartphone. But, a huge problem is it make my PC extremely unstable, even after I stop using it. First of all, it create artifacts all over the place. Desktop wallpaper, app icons, system menubar, ... Some time it delete icon of some app too. This happen after every reboot, I have to reset the wallpaper picture after that. Second, the PC often hang up after a long period of time inactive (no mouse, keyboard input), the only solution is unplug the PC and restart. I left my PC screenlocked overnight, with only 4 Firefox tabs and 1 Pycharm window open, it freeze the next morning. Even after 30min of lunch time, it get laggy, I have to save my works and reboot.
