Fullscreen windows sometimes ignore first mouse click
Affected version
- Debian testing/sid
- Self-built mutter/gnome-shell 40 development snapshots
- Wayland only
Bug summary
Mouse input doesn't work normally at first with some applications which start up in fullscreen mode.
Steps to reproduce
- Configure the Steam client to start up in Big Picture mode
- Exit from the Steam client
- Maximize any window, e.g. a terminal
- Start the Steam client
What happened
Moving around the mouse cursor, you may notice that the cursor shows the image of the maximized window behind the Steam client.
Trying to click any element of the Steam UI doesn't work, the maximized window appears in front instead.
After switching back to the Steam client window, mouse input works normally again.
What did you expect to happen
Mouse input should always work normally.
