Your mcpelauncher-client is compiled as an x11 Application, but your drivers mix it with wayland.

You need a wayland build of the Launcher.

The flatpak is one.

By adding several cmake options you can turn the default x11 only application into an wayland app

You also need to download glfw like in flatpak https://github.com/flathub/io.mrarm.mcpelauncher/blob/3944d0c13704910eb37d5790cf0d11c9ba817d40/io.mrarm.mcpelauncher.json#L212-L217 into the folder glfw_ext (preferable use an absolute path in cmake ...

The default glfw version of this Launcher is too old for proper wayland support.

[ChristopherHX]

GLFW cannot be the default, due to lack of upstream touch screen input support. The touch code only works for the x11 implementation, switching by default to glfw is a loss of functionality and not acceptable for me.
