Artifact on Surface Pro 7

A user reported she encounter something like this on Surface Pro 7:


Looks like the black part was due to some NAN/infinity value in the buffer that stores water amount, as that part was rendered yellow in the Moisture / Tilt panel, meaning the value may be negative infinity?

We suspect it's some hardware error (due to over-heating?), since it would disappear on its own.

If you also encounter similar issue, please let us know. We want to see if it only happens on the Surface Pro 7. Thanks!
