Erratic Cursor Movement

My 2 1/2 year old macbook pro just recently started having some erratic cursor movement/jump - it appears at a new location without the graphical effect of movement.

The erratic movements are strictly horizontal with a mostly right direction jump.

I've cleaned the surface of the track pad. Disabled bluetooth. Ran firstaid on the hard drive -SSD.

When cold booting, the issue does not present until I run a couple of applications. I have 16BG of RAM and don't come even close to using it all.

When using Apple Remote Desktop into my mac, the issue is less obvious but still present. I gather the remote desktop is 'forcing' some control over the cursor, which mitigates the issues a bit.

I'm afraid this may be an Apple support task, but I am hoping that this may be resolved via some software magicy thing.

I would appreciate any ideas into resolving this issue before I need to take it into the Apple store.

Cheers
