Drunk Mouse® when RDPing from a Citrix Session to a Windows 2012 Server

Sure, it’s a deep rabbit hole, but as a consultant I am frequently leveraging Citrix XenApp to get into an environment and then using RDP from that session to get to the servers I really need to work on.  I’ve recently started noticing that when I am connecting to a Windows 2012 Server, the mouse is very slow and jittery.  Very similar to when in a Virtual Machine and hardware acceleration is not enabled.

After a bit of Googlin’ around, turns out the fix is to deselect the Mouse Pointer Shadows on the target 2012 server. 
Instant Speed!

Thank you internet.
