Output size incorrectly reported with xdg-output v3 and fractional scaling
When using xdg-output v3 from mutter master, the reported output size when using fractional scaling is 0x0
.
This is because xdg-output v3 has deprecated the xdg_output.done event and the GDK Wayland backend applies the change as soon as the wl_output.done is received.
That also requires a fix in mutter: mutter!771 (merged)
