I've run into an issue with the behavior of my WPF applications (all of them) since the Anniversary Update. I'm wondering if anyone else has encountered this and what (if anything) you did to fix it.
Problem:
Any control that is based on a list box (or perhaps an items control) behaves strangely if the monitor's display scale is set to anything other than 100%. Menus will disappear as soon as you click them. Menu items/list box items are not highlighted when you mouse over them - or the incorrect ones are highlighted. Clicking them does not select them and so on. Using the keyboard to select them DOES work.
Drag the application to a monitor where the display scale is set to 100% and it works fine. Drag it back, it misbehaves again. It appears as though the application is not properly detecting the mouse position.
I know that the Anniversary Update included display scale changes for WPF. However, I thought they were largely automatic. It would seem that's not entirely true. Any insights would be greatly appreciated.
