Issue/Bug Description:
Vertical screens are ignored when moving app from monitor to monitor. I think this could be realed to different resolutions on the monitors a the app keeps the previous monitor size when IMHO it should adjust to the new monitor resolution/scale

Steps to reproduce (if you know):

1. Setup 3 monitors
2. Set monitor layout as per attachement 1
3. Use shortcuts(Disable auto-tiling: I can't find the related Issue where moving app from monitor to monitor does not work with auto-tiling ON):
   
4. See attachments for issue:
   
   original_layout
   
   after_shortcut: Shift + Ctrl + Super + Down
   
   after_enabling_tiling
   

Expected behavior:
Move app to the monitor on direction to work on all monitor laytouts

Other Notes:
I manage to move app to monitor after multiple iterations of Super + Ctrl + Shift + H | J | K | L but is not consistent

Vertical screens are ignored when moving app from monitor to monitor.

I can confirm windows won't move between displays vertically with the arrow keys shortcuts in adjustment mode when tiling is enabled, only horizontally. After further testing, windows do move up/down vertical displays in adjustment mode when tiling is enabled. The only vertical-movement issue I'm able to reproduce is that windows do not move between displays vertically using the arrow keys in adjustment mode when tiling is disabled. However, Ctrl-Shift-Super-Up/Down does work in this case.

I think this could be realed to different resolutions on the monitors a the app keeps the previous monitor size when IMHO it should adjust to the new monitor resolution/scale

If you have tiling disabled (like your example shows), then there would not be any mechanism to resize the window automatically, so I'm not sure that's an issue. It looks like the window is hanging in between two displays after you move it to a smaller display using the GNOME shortcut, and then when you enable tiling, Pop Shell tiles it onto a different display than you were wanting because more of the window was on that display already.

3. Use shortcuts(Disable auto-tiling: I can't find the related Issue where moving app from monitor to monitor does not work with auto-tiling ON):

That sounds like #522.

Hi,

I also have this weird issue. Mine is dual monitor setup, and when I use the hotkey, the window does not move to the left monitor.
Here is a video demonstration.

@hovo1990 I have the exact same issue as yours, please check #522 or create another issue if you think it is not related.
