Strange Screen Flickering in Full Screen Mode



Windows 10 Home 64bit.
Version 10.0.17763 Build 17763

In full screen mode, when I click on the “File”, “Edit”, “View”, or “Help” at the top left, the entire screen will flicker.

Or when I mouse the cursor over any of the card buttons like: “Insert Above”, “Insert Below”, “Delete Card”, “Add Child”, or “Edit Card”; the entire screen will flicker. Moving the cursor around over these buttons will make the screen flicker repeatedly.
