Thanks for the bug report.
The two most likely causes of this problem are:
* Shell extensions
* Chrome tabs
so you should check each of those separately...
Please delete locally installed shell extensions by running:
cd ~/.local/share/gnome-shell/
rm -rf extensions
and then log in again.
Please also try just closing Chrome when it happens. Does the system
recover?
After you have closed Chrome and deleted all local shell extensions, if
the problem persists then next please provide output from 'top' and 'ps'
while the problem is happening to show the top CPU and memory users.

Title:
mouse pointer becomes laggy after some time and progressively gets
worse
Status in gnome-shell package in Ubuntu:
Incomplete
Bug description:
Over some period of time after logging in the mouse becomes laggy and
eventually unusable.
I generally have a lot of Chrome tabs open.
The time period can be minutes to maybe an hour.
I am not sure if Chrome is required to cause the problem yet but I
have experimented with changed Chrome versions and enable/disable
hardware acceleration in Chrome and that did not make a difference.
