Steam segfaults from libgallium on RPI 5 from Pi Apps build

[Cl0v3rDev]

Hi,

I just installed Steam, box86, and box64 from Pi Apps on my Raspberry Pi 5 and it seems to be unable to launch. It seems to be segfaulting from trying to run a function from libgallium. Here's the short log:

I will also attach the more verbose version if that's helpful too.

The box86 only supports 32-bit x86, and steam only supports 64-bit by default.
Steam is trying to use the OpenGL rendering interface, but the graphics driver on your ARM platform (Mesa/Gallium) doesn't properly handle the x86-to-ARM translated OpenGL calls from Box86.
The mesa driver is not stable.
