My OS version is 20.04. My touchscreen works fine, but when I use my pen the entire OS freezes and even any sound that plays repeats in a loop that is maybe half a second long. The only way I found to get out of this is to force shutdown. I can reproduce this on my laptop without fail. And it is independent of any program I have open. This problem started around 17th March (I don't remember exactly) and update almost every day.
