OK, so I booted up with the mouse in USB3 port. All good.
Put mouse in USB2 port. Problem appears (as expected).

I just tested 5.0.0-23-lowlatency kernel with the mouse plugged into a
USB3 port, and everything seems to be okay. So it does seem to be USB2
specific (I dont have any USB1 ports to test it on, sorry)

Title:
USB mouse cursor lags after
@kaihengfeng - How do I find and install that Kernel? Sorry, I'm used to
just using the gui and command line tools to upgrade, not sure how I
find and install that kernel manually. I am used to using apt for
installing general packages, just this scenario is new to me and I can't
find any
Note that this became 100% consistent. As in every time I booted I got the
issue, rather than just most of the time.
Also, that it's now in release 5.0.0.20-lowlatency, 64 bit version.

Also, that it's now in 5.0xxx

I have the same issue.
At the login screen, I select my user, enter the password, the mouse works fine
at this point.
Click on login, wait, screen comes up then at random, the mouse either
works fine (about 1 time in 5) or it goes really really slow (4 times out of 5).
Only way I'm working
