I have some custom functions with associated shortcuts which move the active window to a nominated display (e.g. move active window to display #3). They work perfectly except for an issue I see with a specific application: Devolutions Remote Desktop Manager.
Starting with RDM maximised on my primary display I'm seeing the following behaviour:

• On entering the shortcut to move to another display, the window will very briefly move to the target display (a fraction of a second, short enough that it won't have finished drawing), and then immediately return to the original display. The same will occur on any subsequent attempts.
• On restoring the window, the window will appear on the desired display with dimensions set to occupy the full display viewport. The window appears to be in a somewhat confused state at this point. For example, opening a menu in the titlebar will result in the menu button being highlighted, but the menu not appearing.
• On maximising the window, it will return to the primary display.
• Above sequence of steps can be performed again with same results.

There's I think some tie-in to the display topology/resolution/scaling. In my typical setup I have the following configuration:

• Primary display (3840x2160 & 200% scaling)
• 3rd display directly above primary display (3840x2160 & 200% scaling)
• 2nd display to the right and vertically centered between primary & 3rd display (1920x1200 & 100% scaling)

If I first move RDM to the 2nd display and then the 3rd display, it works as expected. This isn't a big issue but it is annoying.
Tested on DisplayFusion v9.7.1 and v9.7.2b5 with RDM v2020.3.23.0 x64.
