Simple demo run ok

So the RK3568 is an embedded board running ubuntu Linux?

Looking at the screenshot: Looks to me like some graphics-related driver is not available. What kind of environment do you plan to run on? Wayland with DRI?

I'd start with trying some other application using 3D acceleration. If that does not come up either: Check the packages in ubuntu for anything DRI related and try installing those. Sorry, my ubuntu-foo is a bit limited, especially on ARM hardware.

https://forum.radxa.com/t/ubuntu-20-02-mali-drivers/12373/6 might help, but I am not sure ;-)

Here is the screen on Sep 15,but after running cargo clean,rebuild the demo,it doesnt't work well(slint ="1.2.2" as well)

thread 'main' panicked at 'Failed to set icons: XError { description: "GLXBadContextTag", error_code: 156, request_code: 146, minor_code: 16 }', /home/rpdzkj/.cargo/registry/src/index.crates.io-6f17d22bba15001f/winit-0.28.7/src/platform_impl/linux/x11/window.rs:1008:10

The folllowing is Cargo.toml same as Sep 15

the crash happens in winit. Not sure we can do much about it in Slint.
Since the error message hints about icons, are you by any chance setting a window icon? (by default, there is none but that shouldn't be a problem)
But the fact is that seems to be related to the GL driver.
You can also try to use SLINT_BACKEND=winit-software to use the software renderer instead of OpenGL

Another idea: In the configuration of your X server, could you try adding a section to disable GLX? Like this:

Section "Extensions"
    Option "GLX" "Disable"
EndSection

You can put that into a file (say disable-glx.conf) and drop it in /etc/X11/xorg.conf.d/. After that you need to restart your X server.
