Trackpad Issues since updating to Mavericks

I have a Mid 2010 MBP, which I recently updated to Mavericks. Ever since the update I've had two issues: intermittent graphics glitches around my dock and application labels etc (a quick search showed that this is quite common and has no fix yet...), and a really frustrating issue with my trackpad. After a certain amount of uptime - sometimes as little as a few minutes, sometimes hours - my trackpad decides it is now in charge and goes crazy, clicking, dragging, scrolling and opening exposé (essentially, performing all of the touch functions on its own). I've searched and found many people have had similar issues with trackpads, but not intermittently like mine - a restart temporarily remedies the problem. I've reset NVRAM and the SMC, cleaned out the trackpad, reinstalled Mav from scratch after completely reformatting my hard drive, and yet it's still being a nuisance. I really don't want to have to downgrade, is there anything else I can try??
