Same here. A friend and I realized we had the same issue on certain situations. The clicks were more noticeable while scrolling, ie. Pycharm. I also realized it while zooming the map here: https://es.flightaware.com/live/

After going back to a version less than 5.3.0-46 it gets fixed, so seems to be a conflict on 5.3.0-46. I know this bug isn't about Ubuntu itself, but might help someone googlin' it

Yes, I'm Agustin friend. and in my case was with Kubuntu 19.10 and kernel 5.3.0-46.39 and It happened to me when using scroll in any Idea Ide like intelliJ. The problem fixed rolling back to 5.3.0-45

In a Lenovo thinkpad T460. It happens with or without another monitor connected and no matter is on battery or pluged in

its also there in xubuntu 20.04 with kernel 5.4.0.26

i found same problem in this link:
https://www.reddit.com/r/Dell/comments/3ta1gl/dell_xps_13_9350_buzzing_noise/

and i guess intel graphic card caused this problem

i taked diff bettween "modinfo i915" in kernel 5.4.0.26 and 5.3.0.45:
how can i tested more things?
or how can i roll back each file for find buggy file?

I found that it called coil whine.
It is not a linux bug but it's a common laptops issue.
But i still looking for how kernel 5.4.0.45 hadn't this problem.
