I’m not able to reproduce this issue that I can see on a Mac laptop or on one of our Razor laptops.
You may want to make sure that the correct GPU is being used when you test though because in the DxDiag it was showing that the Intel HD Graphics 530 was being used instead of the Nvidia GPU that is listed on Alienwares site.
You may want to see if it’s not something with the trackpad for the mouse by using a wireless usb mouse or wired mouse.
