stacked display and moving windows with modifier keys

I’m using a macbook with a second display stacked above the main display and I’m having trouble moving windows with modifier key; I can’t move the a window into the top display, it’s blocked at the top of the main display. Is this a known?

  • dragging by a window’s top bar works just fine.

I remember there was some API limitation, possible related to macOS "Displays Have Separate Spaces" setting. I'll check later, but I think this might not be possible to fix.

As a workaround, the drag will cross the display boundary if it’s fast enough.

Could you try to disable this option? Maybe the check doesn't handle stacked displays correctly:

No difference.
