When working in Pro 2017 I am finding that any clip of any size that I try to play in the Viewer Window plays choppy and with lag in any workspace layout (Classic, Composite, All Panels) except Edit. Any clip of any size plays nice and smoothly in Edit, but in none of the other workspace layouts. I have never had this happen in any of my other versions of Hitfilm (going back to 2 Ultimate). Even if I adjust the size of the window, there is no change. The Media Trimmer Window plays anything in the Media Panel with no choppiness or lag. It is a very interesting situation. Any ideas?
EDIT by Cedric: changed the title for clarity. Was "Lag and Choppy Playback in Any Workspace Layout Except Edit".
