It seems that vulkan render cause the problem, opengl render works well

config in `~/.config/kdeglobals`:

> [QtQuickRendererSettings]
> SceneGraphBackend=opengl

instead of

> [QtQuickRendererSettings]
> SceneGraphBackend=vulkan

Makes sense because kwin still doesn't support vulkan. On Wayland, kwin forces opengl for qtquick.

Enforce OpenGL for QtQuick on x11 when OpenGL compositing

Using some other graphics API like Vulkan for QtQuick
together with OpenGL is not not supported and can lead
to crashes.
