[Bug]: The maximized window remembers its state and it causes a problem.

[yoonsangmin]

Before you make the issue, confirm that

• You are running the master build from GitHub actions
• You have read the FAQ and the usage instructions
• You have searched pull requests and issues and have found none similar to your issue
• This problem comes from a failure in the tiling system and not a missing feature

Describe the bug

Most KDE apps remember the maximized state. If you close the app while it's maximized, when you reopen it, it will tile in a maximized state. If you unmaximize it in that state, empty space appears in the tiled area. Even if you maximize it again, it stays tiled in the maximized state. The only solution is to either drag the window or use a shortcut to make it a floating window.

To reproduce

Close the window after maximizing it, and then reopen the application. Unmaximize the maximized window.

Expected behavior

A tiled window always opens in an unmaximized state, or if you cannot unmaximize it, a maximized window should avoid tiling.

I just found out that there is a latest version in the action. I confirmed that the issue of creating empty space is not present in the latest version.
However, it still remembers the maximized state, and when reopened, it tiles in the maximized state.

It would be good if the application, when opened in a maximized state, does not tile, and stays maximized, or the application automatically unmaximizes when tiled.

can confirm I'm getting this behaviour too as of the latest commit

[zeroxoneafour]

I recommend adding a window rule to KWin that sets the maximized state to false for new windows. KWin doesn't actually have a property for whether a window is maximized or not, so it's hard to tell if a window is maximized when added.
