Minimize electrical interference with a mat

Electrical Interference causes the mouse to be jumpy.  When I remove myself from that desk and go elsewhere, the jumpiness stops.

Is there a pad or something that will potentially result in less interference?

Is this a guess or a proven fact that you are in high electrical interference area at your desk?  What is the interference from? Solutions will range from an ESD mat on your desk to a farady cage

Is this a wireless mouse or wired mouse?  what brand?  If it is a cheap mouse, that could be a cause as it may not be shielded enough.
Some tests you can try is trying moving further away from the mouse, and how far away do you need to be in order for the 'jumpiness' to stop?

Another test is to wrap the mouse in foil (other than the bottom of the mouse) and see if the jumpiness stops. (Foil may not be an excellent test, but might help some).  See if the jumpiness lessens at any case.  

Another thought too is to turn the mouse upside down, so that the eye/laser is not sensing anything, does the jumpiness stop?

Something else just popped into my head, does this happen with this specific mouse or any/all mices?

Can you try a different one and see if this helps?

Sounds more like RF interference on a wireless mouse. When bad, are you near an access point or other radio device? Is your cell phone too close to your computer?

i also would first test with another,  wired mouse, to be sure it's not a mouse problem

I believe he said the mouse works when he moves to another location.  BUT, is this an external mouse, or are you experiencing this on the built in touch pad? More clues please.

I would try a different mouse for sure. Dry time of the year here and static electricity is sometimes an issue, but once grounded by sitting down and perhaps touching the desk, electrical interference will likely be gone. So try a better mouse.

I'm using the built-in touchpad for the Windows Surface 4 Pro.  When I move to another location, it goes away.  I am not sure if it's a Radio Frequency (RF) problem or an Electrostatic Discharge (ESD) problem, but I tried putting it on a thin rubber mat and the problem goes away. Based on that result, I would guess ESD.

There must be something strange about the location. Try an external mouse
Commented:
I have seen this behavior on touch pads before because most are capacitive in nature and can be effected in strange ways. That is why I wondered if it was an internal touch pad rather than a “mouse” as you described it.

Just curious, does turning down the sensitivity on the touch pad help with the issue? Sometimes if they are set too “fast” small changes in even tempature can cause the cursor to jump about.  You might be able to solve most of the problem just by slowing down the cursor speed.

Also, check for an updated driver. I know that there have been changes to trackpad drivers in the past (past jobs) that were designed to look for small changes like you are seeing and damp them out.

Also see this article 'Specifically' about the Windows Surface Pro having this issue and how to potentially resolve it:
https://windowsreport.com/mouse-jumps-surface-pro-4/

Please look over some of those solutions and see if any of those resolve your issues.  I'd cut and paste but there's a lot there and the link I feel is sufficient.

Slowing the mouse down helped, as did a rubber mat.
