[Bug]: directional hotkeys are inverted on vertical monitors

[alextremblay]

Issue type

Multi-monitor / workspaces

What happened? (actual behavior)

I have two monitors. one configured in omni as horizontal, one as vertical

I have hotkeys configured to focus left, right, up, down and to move windows left, right, up, down

When i focus / move windows on my main (horizontal) monitor, everything works correctly

When i move two windows onto my second display, things get weird. the windows tile horizontally (see pic attached below

with the left window focused, as seen in the screenshot, focusing right does nothing. Focusing up focuses the right window

and focusing down moves focus to the left window

if i hit the keyboard shortcut to move the left window into the right one, they form a vertical stack. Trying to move focus up and down the stack does nothing, but moving focus left / right causes focus to move up/down the stack

Also note, if i manually configure the window's orientation to "Horizontal", none of these issues occur. I will keep doing that for now as a workaround

What did you expect?

focusing / moving left <---> right should cause windows to focus / move left <---> right
focusing / moving up <---> down should cause windows to focus / move up <---> down

Reproduction steps

1. Connect a second display, allow it to pick up the correct orientation ("Vertical") from MacOS
2. Move two or more windows to it
3. try to navigate / move windows directionally, the directions are swapped (up = left, down = right)
