I notice a weird lag while scrolling in some word documents. It takes almost 2 sec for the word to react on scrolling and when it does it goes line by line. Same thing when I actually click on the scrolling bar of the document. Usually happens when I open 2 documents or more. Is there a way to temporary fix it? I cannot wait for Microsoft to release an update.
I had the same problem. A workaround that fixed it was turning off animated controls:
In Word, go to Control panel > System and security > System > Advanced system settings (in upper-left side) > Advanced tab > Settings in Performance box > Visual effects: Here disable Animate controls and elements inside windows.
