Dragging Window is very sluggish

Hello Community,

when moving my LR CC Programm Window across my Monitors (3) it moves so increadably slow and behaves very sluggish. It seems as its trying to align to a desktop grid to snap to or something. With LR classic or Photoshop, I don´t have such issues. It´s just the LR CC. I have no performance issues otherwise, when working with LR CC or any other Adobe Programms for that matter.

Does this read familiar to anyone? 

regards
