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.

Hi Owen,

Requested file attached. I attempted to move the RDM window to the other display per my original description three times, around a second each apart, starting at ~9:06PM AEDT. Let me know if I can provide any other information to assist. Thanks!

Just tested on v9.7.2 Beta 6 but issue remains I'm afraid. Let me know if there's any further data I can provide to assist with isolating what's going on.

No problem, I've attached the requested settings export. The video I may not be able to get to until the weekend.

Hi Owen,

I've also attached a short video from my smartphone showing the issue. The few capture tools I tried either didn't work well with capturing multiple displays simultaneously, or didn't reliably capture the issue.

In the video you can see me attempt to move the RDM window from display #1 to display #3 by pressing the key combination for my "Move window to monitor #3" function. I attempt the move three times in succession.

Thanks!

No change I'm afraid. I tried restarting DisplayFusion too after changing the setting just-in-case.

Thanks Owen, that's great. It's not a big issue, but everything else in DisplayFusion works beautifully, so I keep noticing it as the one rough edge!

Just a quick note that I also just witnessed the same behaviour with a fullscreen PuTTY window, so whatever's going on isn't specific to the RDM application.

Just noting the issue is still present in the recently released v9.8.

Just wondering if there's been any movement on this issue? It's a bit of a bugbear for me as it breaks various functionality from working on affected windows. I have no idea how difficult it is to fix though, so appreciate this may just not make the cut for the foreseeable future.

Thanks Owen!
