What you did

Describe how you arrived at the problem. If you can, consider providing a code snippet or link.

cargo run --example window_resizing

and also,

cargo run --example window_resizing --features wayland

I resized the window to the fullscreen by clicking the maximaize button and clicked on the screen.

What went wrong

The window behind the Bevy window took focus. This seems to occur under the following conditions:

1. When the Bevy window is fullscreen.
2. When there is another window (browser, file explorer, etc.) behind the Bevy window and at the clicking point.
3. When clicking specific area, the brighter darker area.
   

Additional information

Also, screen resizing in the usual way using the mouse does not work. Even if I move the mouse to the corner of the screen, the mouse icon does not change to a resizing icon.

I tried updating the system by yay -Syu and rebooting.

I tried it again today and it works fine.
No focus is lost, resizing works fine.
I didn't change any code, and my local environment is the same.

I too use the GNOME desktop and been having similar issues recently in other apps (though not Bevy, or any Rust/winit apps for that matter). I don't believe that there's anything that can be done to fix this. I'd guess it's some obscure GNOME/Mutter bug.
