Contextmenus on dpi-aware application have a wrong scaling #262
Description
Situation : multimonitor setup:
- monitor 1 : 4k with 125% scaling
- monitor 2 : HD with 100% scaling
Application runs on second monitor : the contextmenu's on the document & anchorable's Tab are too large (scaled on 125%?).
I narrowed it don toe the DropDownControlArea class where the DropDowncontextMenu.PlacementTarget is null. Since the target is not defined, wpf assumes the scaling of the main monitor (125%) and shows the contextmenu far too large.
Include a patch file with the fix
