Issue description

After changing the "Linux Display Server" in the "Project Settings" to "wayland" (Project Settings -> Display Server -> Driver.linuxbsd -> wayland), when changing the project resolution "in-game", in Windowed Mode, the project window doesn't resize and center automatically, contrary to the expected behavior when the "Linux Display Server" is set to "default" or "x11", as demonstrated below.

"Linux Display Server" set to "default":

"Linux Display Server" set to "wayland":

It does, however, adapt the project window size if changed manually, by dragging the window border.

As this seems to be an issue specifically with Wayland as the compositor, I include here my system information, obtained with fastfetch, to better help solve the issue:

Steps to reproduce

• Change the "Linux Display Server" in the "Project Settings" to "Wayland" (Project Settings -> Display Server -> Driver.linuxbsd -> wayland)
• Change resolution using get_window().set_size()
• Repeat but with "Linux Display Server" set to "default" or "x11" (Project Settings -> Display Server -> Driver.linuxbsd -> default) to see expected behavior

The MRP included below has a simple option button to set different resolutions for better testing, as well as the background godot icon to help see the issue better.
