A random window becomes "always-on-bottom" frequently

[aresler]

yabai-v7.1.6

After a period of normal usage (creating spaces, moving/swapping windows around), any random window can occasionally become "always-on-bottom", which is exactly the opposite of "always-on-top" (for the lack of better term). Meaning it is always hidden behind any other window on top of it. The only solution is to quit and restart the app that is drawing this window.

I don't see any errors in the log.

I haven't found reliable steps to reproduce it, but it happens about every ~15 minutes of normal usage. I don't have any obvious toggles that can do that in my rc files (attached). I'm happy to collect any data about the window if needed.

UPD: Just reproduced the issue as follows:

1. Destroyed a 3rd space with a window on it
2. The window moved to the 1st space
3. I moved the window to the 2nd space, that had some other windows in floating mode

I can now focus the said window from the mission control, but it's always covered by other windows.

Here's the query for the window after reproducing the issue:

}

I'm concerned by the "sub-level":-20,. When the issue is not reproducing, the sub-level is 0 for all windows.

Well, this issue makes yabai plain unusable because after swapping few window around, the issue is reproduced and I have to restart the apps. Almost every time.
