Hello, verifying the engine and even a brand new windows install does not fix the problem. I can only get it to work if I go into high contrast mode for windows theme. Otherwise the menus only appear if I click on the menu item and press “spacebar” to show the options. Many client projects are on 4.13 or lower, so this is a pretty big issue at the moment. This does not happen with other windows applications as far as I can see.
