For weeks I am having a problem with Sony Vegas Pro 13, that when I change something with FX it doesn't show up in the preview as it normally does. It only shows up after closing the FX-window.
I've already tried to reset and uninstall Sony Vegas, but nothing worked.
Windows update to 1703 changed both Intel & NVidia drivers. Needed to re install older driver set which fortunately I had pre-saved. Understand the rest of Creator updates due mid October.
