Hello David,

could you set the SDL_VIDEODRIVER as a permanent environment variable?
Maybe there is a workaround with this package [1] but I don't have high 
hopes for that.
The Arch Linux Wiki [2] states:

> To run a SDL2 application on Wayland, set |SDL_VIDEODRIVER=wayland|.
>
> Note: Many proprietary games come bundled with old versions of SDL,

> XWayland, set |SDL_VIDEODRIVER=x11|.

P.S.: just ignore the dude. everybody here does so.

I'm running GNOME under wayland on Alpine 3.11. It works almost

$ ./molko

$ glxgears
