Removing this line seems to fix wayland as well as x11 (xwayland)

Simply removing this line would be incorrect, because then the windows would always be considered focused. If we can reassure that Winit will always send a WindowEvent::Focused(true) event after creating the window, we could replace feature = "wayland with any(feature = "wayland", feature = "x11").

However, I couldn't reproduce the long startup time bug using x11 on my machine (XWayland Version 23.1.2).

I am using the same xwayland version and I can reproduce the long startup time on sway (version 1.8.1)

Ok, I could also reproduce the issue when using X11 through XWayland on Sway. but not when using X11 through XWayland on Gnome.

I tried out treating X11 the same as Wayland and tested X11 on

• Gnome (Xorg)
• Gnome (Wayland) using XWayland
• Sway using XWayland

The long startup time was fixed in all three cases, but Sway showed a small delay (around 1 second) which I believe had to do with the fact that I have an Nvidia GPU and had to use the --unsupported-gpu option. It would be nice if you could confirm that there is no issue using X11 on Sway with the latest commit.

Thanks for looking into this! With the latest commit running a xwayland bevy app has no startup delay.

I don't think this is a Nvidia GPU problem. I have an AMD GPU and experience around 4 sec startup delay with a native wayland bevy app. This delay does not exist on xwayland bevy for me.
