Gentlemen!
Myself and one other colleague of mine had the same exact problem! I tried VW support, IT at my job, several friends different forums, everything I could think of and everything failed. Finally I fixed mine by purchasing a 4K monitor which is the same resolution as my MSI. All my other monitors are 1920x1080. When I changed my computer to match my other screens the cursor got even bigger! What made me decide to get the 4K was when I would drag the VW to the MSI, the cursor was normal size.
There's more I could say about it but, I'm way behind in work and I need to catch up. If anyone would like to ask a question feel free.
