Windows tile over other tiled windows sometimes

Bug report

I've reported this issue in #159 (comment) previously.

I've been having a very similar issue lately which I can't reliably reproduce, where yabai loses some of its managed windows so new windows tile over them. Here's a screencast: https://streamable.com/h6fau

Your idea of resetting the space by destroying the current one works quite smoothly, so I wrote a small script that creates a new space, moves it so it's right next to the current one and then destroys the current one, thus moving all windows over to the newly created space and keeping the order of spaces as if nothing ever happened.

# reset current (non-fullscreen) space
yabai -m query --spaces --space | jq -er '."native-fullscreen" == 0' > /dev/null && \
    yabai -m space --create && \
    seq "$(yabai -m query --spaces --display | jq -r 'map(select(."native-fullscreen" == 0).index)[-1]')" \
        "$(yabai -m query --spaces --space | jq -r '.index + 1')" \
        | sed '$d' \
        | xargs -I{} yabai -m space {} --move prev && \
    yabai -m space --destroy

I have this set to a keyboard shortcut in skhd so I can easily reset the current space.

It's not a fix, but it's at least a working bandaid.

Now I've gotten this issue again and tried to query whether any state was messed up.

Nothing wrong with the windows: It shows 3 tiled windows, however 2 have the same frame.

yabai -m query --windows --space | jq 'map({app: .app, floating: .floating, frame: .frame})'

[
  {
    "app": "iTerm2",
    "floating": 0,
    "frame": {
      "x": 850,
      "y": 42,
      "w": 810,
      "h": 988
    }
  },
  {
    "app": "Google Chrome",
    "floating": 0,
    "frame": {
      "x": 850,
      "y": 42,
      "w": 810,
      "h": 988
    }
  },
  {
    "app": "Google Chrome",
    "floating": 0,
    "frame": {
      "x": 20,
      "y": 42,
      "w": 810,
      "h": 988
    }
  }
]

Now here's what's weird: The first-window attribute of the space is 0.

yabai -m query --spaces --space | jq

{
	"id": 58,
	"index": 1,
	"display": 1,
	"windows": [
		1992,
		1626,
		109
	],
	"type": "bsp",
	"visible": 1,
	"focused": 1,
	"native-fullscreen": 0,
	"first-window": 0,
	"last-window": 1992
}

I do not know what triggers this behaviour and cannot reproduce it reliably. I've had this multiple times on both 10.14.6 and 10.15 over the last two weeks or so.

It seems like something gets messed up with how yabai manages the space as the only way to properly fix the issue without restarting yabai or moving all windows to other spaces is to destroy the space.

Just wanted to chime in that I've noticed the same issue, happens intermittently and I haven't been able to figure out a cause yet...

This issue is only present on master, and not in the latest stable release.

The underlaying problem of this issue is present in earlier versions, but did not manifest for some reason. Fixed on master.
