Window Snapped to incorrect screen after moving window to other monitor.

[globalhuman]

Bug: I have two monitors. 1 Landscape and 1 Portrait. If I have a window on the portrait screen and shift it to the Landscape screen (and vise-versa) and attempt to use the keyboard shortcuts to snap to the left/right/top/bottom then the window snaps back to the portrait screen.

Workaround: If I interact with the window after moving from portrait to the landscape monitor and then attempt to snap to the left/right/top/bottom it works fine.

Help: I have had this issue for a while but am looking for either a workaround with keyboard shortcuts or if there is a potential fix.

I am no JS coder but I took a quick look at the code today and noticed the cursor position was used in tiling.js which made me experiment.

With the above description. If I move the cursor to the monitor that the window has moved to the accelerator bindings work fine. If I leave the cursor where the window originally was the window snaps back to this original monitor.

I also experimented with having "Group edge tiling" and "Keep the window group maximised" enabled which strangely worked like I would expect. The cursor did not dictate where the snapping occurred. The only issue with this is that I must firstly maximise a window before moving it.

Can I buy someone a coffee$ to take a look at this?

I can also add that when "Grouping edge tiling" is enabled, the problem is gone, except however, I do not wish to use that setting.

alas...

Hi, I experience the same issue, having an external monitor plugged to a notebook.

When moving the window from one screen to the other (for example, pressing shift + "windows" + arrow), if I try to change its position using ctrl + "windows" + arrow, it goes back to the screen it previously was.

As mentioned, if I interact with the window after moving it from one screen to the other, by clicking, or moving it with the mouse, then it works as expected.

I forgot to mention, I am using Ubuntu 21.04, and ShellTile version 65, with the options of the attached image.
