Strange isssue with mouse when copying files

I am having a strange issue with my wireless mouse. Any time I am copying files to a local or network location my mouse gets very jumpy and almost unusable. My trackpad works fine though. The mouse does not do this on other computers. This is happening on the Samsung laptop I have listed.

It is very unlikely this is an interference issue even if you are copying over a wireless connection. try on a wired mouse ... to me it sounds like a resource bog.

Wired works fine. The strange thing is, when I am editing and encoding videos, I have more resource usage, yet the mouse is fine.

did you try uninstalling and reinstalling drivers?

Yes.
