Very recently after the 411 update when I am trying to add a chrome key, or titles, or even adjust the pan and crop the preview window won't update until I close the effect and click away from the affected clip and back onto it on the timeline. This is very frustrating when trying to fine tune the sliders on a chroma key or anything else for that matter. Has anyone else noticed this or similar problems? For added info I often use 4K footage and create video proxy files for them for smoother performance.
My system stats are in my signature. Thank you.
