[bug] Window not showing on Wayland

[Tim-Paik]

Valid for all examples
tag: tao-v0.12.1 everything is normal
tag: tao-v0.13.0 window does not display, taskbar icons are created normally
Everything works fine in x11 mode (using GDK_BACKEND=x11 environment variable)

Environment
› OS: Arch Linux Rolling Release X64
› DE: GNOME 42.3 + Wayland
› rustup: 1.25.1
› rustc: 1.62.1
› cargo: 1.62.1
› Rust toolchain: stable-x86_64-unknown-linux-gnu

Does the frame of the window still show up?
Could you test if it's caused by this PR?

The window frame is not displayed. For the latter, I think yes, b905852 can be displayed normally, but not after db7e5cb

Okay I got a wayland setup and found disabling double buffer cause this.
I'll need to find out if it can be painted by GL libraries when remove that line.
But I haven't done wayland support yet.
If you are urgent, I can comment out that line first as patch.

It's not a big problem for me, my application is still stuck in tao 0.12.1, and I can use the x11 backend to avoid it in my development. But hopefully this issue doesn't affect tauri, which would break native Wayland support.
Thanks for your work!
