In a multi monitor scenario with different scalings and an application that is configured to run ‚per monitor dpi awareness‘ a floating toolwindow cannot be docked at all positions.

Example:

Monitor 1: 1920 x 1200 (100%), Monitor 2: 2048 x 2560 (150%)

Our WPF application has a main window, maximized on screen 1 and a child window maximized on screen 2.

In the app.manifest we use per monitor dpi awareness.

Both windows have a RadDocking instance with a docked RadPane. Start the application, undock a tool window and try to dock it at the right position on monitor 1.

è It is not possible since the compass is deactivated before the mouse cursor reaches the right monitor area.
