Public bug reported:
I have a Lenovo Thinkpad X1 Yoga 4th Gen. 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.
