My Mac Pro recently started giving me mouse stutter. At first I thought it was my wireless mouse (non-apple), so I switched to other mice (one an HP, the other the original mac mouse that came with my Mac Pro) and still see the same problem. Also, I see the same thing whether I'm running on MacOS or in Windows via Bootcamp. Clearly appears to be a hardware level issue within my Mac Pro, but not sure what, if any thing I can do about it. Any ideas?
