Ghost Keystrokes/Touches and Stuck Keys on Surface Studio 2

I am working with a customer who has purchased two SS2s, and both have the same issue when connected to the Surface Dock 2. After a few minutes, the system will start detecting input (seems like touch input) in random places, and the keys on the keyboard will type erroneously. Often, it will start typing double letters (for example, dog would be ddoogg) and adjacent letters.

This occurs with both of our SS2s, which are brand new, and we have confirmed the issue with two Surface Dock 2 units. We have not tested with the Surface Dock 1. We have not had any issues with using the standard charger and a USB-C Hub rather than the Surface Dock. We also have multiple Surface Books (the majority of our fleet) which have no problem with these docks.

I initially expected this to be a heat-related issue, but the SS2 stays quite cool even when stress testing. It has something to do with the input drivers or actual hardware when connected to the dock. I appreciate any assistance, and I will be contacting technical support as well.
