Acer Aspire R7-572 Touch Screen Glitching Out

I recently purchased an Acer Aspire R7-572-6423 touchscreen notebook. It works great for the most part except for the touchscreen seems to glitch out every once in a while. What happens is out of nowhere the touch screen will start registering a click in the very upper left corner of the screen (as seen by the Windows 8 touch visual feedback) even though I am not touching the screen. The clicking happens very fast (several times a second) and makes the notebook unusuable.

I can make the clicking stop by touching and holding my finger on the screen near where the clicking is happening. However, as soon as I lift my finger, the clicking resumes.

To fix the issue, I have to do a touch screen calibration (Windows settings -> Tablet PC Settings -> Calibrate -> Touch input). However, the calibration appears to be off using this method (I cannot swipe the windows 8 bar to the right) so I then do a calibration reset (Tablet PC Settings -> Reset). This generally resolves the issue for a while.
