Serious sam classic doesn't work on raspberry pi 500

[mailtowim]

On raspberry pi 500, you can start serious sam classic, but you only see an icon on the taskbar and sound out of the soundcard.
No window is created.

I tried the snapcraft version and i also tried a local build (including the vulkan version).

I am using the default raspberry pi os (based on bookworm).
