HP Probook, both slow and high CPU/GPU using docking (2 screens)

Hi,
I have a brand new HP Probook 445, and using the HP universal USB-c docking G2. I experience an annoying lag to anything happening on the screens, just when moving windows across screens, interacting with say Firefox GUI, or especially when using something that takes all screen (Google Earth, Remote Desktop, etc). Everything is updated on the computer (bios, chipset, graphics, firmware). Is this a known problem? I wonder if I have to return the computer, or what. The problem is only happening when using docking and DisplayPorts.

Well, I have exactly the same on my old Lenovo Laptop T430, what helps is restarting the Windows Management Instrumentation.... I have no idea what causes this, but when I restart that service, the lagging is usually gone. Note that this also happens using Linux, but then I have not found the process yet that causes this. It must have to do something with the driver I suppose.
