Ops, I meant "unmaximize"!
Comment 2 Nate Graham 2021-06-08 19:43:40 UTC 
1. Do you have the "Maximizing" window placement mode set, by any chance?

2. What happens if yo manually drag the window somewhere else, resize it to be as small as it can be, maximize it, and then un-maximize it?
Comment 3 Lua 2021-06-09 15:42:46 UTC 
1. No
2. I can't resize the window. If I press "restore", nothing happens
Comment 4 Lua 2021-06-09 15:47:50 UTC 
I use the "centered" window placement. Also, I don't have any window rules for Settings.
Comment 5 Nate Graham 2021-06-09 16:29:22 UTC 
Ok. So can you drag the window somewhere else and resize it by the corners or edges?
Comment 6 Lua 2021-06-09 16:56:54 UTC 
Yes, I can do this. Also, after doing it, I can restore and maximize the window again.

I changed the window placement back to minimal overlapping, but it didn't work.
Comment 7 Nate Graham 2021-06-09 17:02:44 UTC 
Right.

So the bug is that when you maximize a window on wayland and then quit and re-launch the app, the window is opened with the *geometry* of a maximized window, but not the *state* so clicking the maximize and un-maximize buttons don't seem to do anything because the maximized and non-maximized sizes are identical.

I probably mis-triaged this bug. That said, I cannot reproduce the specific issue described here. Instead I experience a different one: when I maximize System Settings, quit it, and re-launch it, it doesn't open in the maximized state. I've filed Bug 478443 for that.
