Public bug reported:
After installing ubuntu 20.04, I have an issue with my mouse pointer
lagging a lot.
It happens on my trackpad, physical mouse, wacom tablet, and trackpoint.
It's only a graphical issue (ie: The underlying whatever is actually
moving. The visible pointer just isn't).
Other mouse moving related actions do not exhibit the same behaviour.
Window dragging is smooth. Applications that use custom mouse pointers,
such as krita, work smoothly.
The issue persists both on nVidia graphics and intel integrated
graphics.
I am using a lenovo thinkpad p50.
The issue persists constantly when I am using the in built laptop
screen. However, when I connect a second monitor, it only happens
occasionally.
I installed ubuntu 20.04 from a usb drive, keeping my home partition
from 18.04.
