other electronics (including a desk lamp).

I have a usb switch with a wireless logitech mouse and keyboard
connected to it and a wacom intuos tablet (with mouse) hooked up as
well.
The mousepointer always makes the small jumps at a specific location
in the website.. so it's not something that happens all over the
webpage.. it just seems like a particular spot on the webpage that is
magnetic and the mousepointer jumps to that location when it comes
near.
I turned off a bunch of plugins and at the moment I can't seem to
replicate the problem. But if it turns up again I will perform your
suggested experiments to see if I can figure out what plugin was
causing the problem. Here are some screenshots to show which plugins I
have enabled and disabled:
