In my case with Parrot Linux it was a case of Interrupt conflicts.
IRQ#18 kept being disabled by the system. After disabling the EHCI
Handoff in the BIOS,ehci_hcd:usb1 was replaced with ehci_hcd:usb2 and
the mouse lag after a random period of time stopped.

My PC had this issue. It was an Intel chip and a Logitech mouse,
keyboard. Over Christmas, I upgraded my desktop. The issue has gone away
now. I'm still using my Logitech keyboard and an Intel chip.

I also have this issue.
Plugging it in to a USB3 port solves the issue, but I don't want to waste my
precious USB3 ports for a mouse.
I experienced the issue with Ubuntu Studio 19.04, 19.10.
With 18.04 it works fine.

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)

So it's specific to AMD systems.
Does this only happened to EHCI (USB 2.0) ports? Does this happen when
it's connected to xHCI (USB 3.0)?

I just tried Ubuntu Studio 19.10 which uses kernel 5.2.0-8-lowlatency,

I tried now with 'linux-generic' package (provides currently linux-
image-5.0.0-20-generic). I did not experience any mouse lag issues,
upon any successful* boot. So in that sense this is 0/10 reproducible
with 'generic' kernel variant.
With 'lowlatency' kernel the mouse lag issue is roughly

I just saw this right at boot. The mouse was lagging already at the
login screen. And the login screen took around 10 seconds to show up
after the first two lines of kernel boot messages. (Usually takes around
2 seconds).

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

It is an kernel issue.
I tested with all 4.15.* kernels available in the ubuntu repo, but only
upgrading the kernel to 4.16.0-041600-lowlatency from [1] solved all issues.
don't have time to test other distros, sorry
how can I help now?
