Many notebooks including the Dell XPS 13 now have 4k displays, ever since I bought this notebook I noticed issues when I RDP’d into my servers or home laptop with the mouse behaving very wierdly.
The mouse would rapidly switch from guest to host mode when trying to control some windows VMs, at first I thought it was a vmware tools issue or possible the touchpad or touchscreen but I eventually found the solution!
You must disable display scaling on the vmware vsphere application and all the woes vanish!
I hope this helps some others, it was driving me insane! I was about to buy a new laptop!
