I'm affected by what seems to be the same bug or a very similar one. Also Ubuntu 19.10 fresh install. Additional information from what I have observed on my machine : - It's not only the cursor that stutters but the whole machine freezes for an instant. It's most noticeable while scrolling or watching videos. - it does not start right away. Maybe after suspend ? I'm not yet sure. - I have the same information re the Inter wireless 8260 driver than mentioned by the other user (namely that it does not function). - On the other hand, I have tried disabling Wifi but it did not seem to have any effect (I will check again). Here are the dmesg and lpsci text files. Thanks for your help.

I did a fresh install (deleting and overwriting 19.04 with 19.10). For example: When I want to go to a button the cursor sometimes stops on the way to it and moves on milliseconds later. In Ubuntu Ubuntu 19.04 (which is my daily driver for now) this behavior is not present.
