Pretty sure this is now the cause of my latest AppImage build as of main today to now crash with a Core Dump. I have a System76 machine with dual GPUs running in hybrid mode.

I went back to the commits before this change and the build runs perfectly fine.

Works:
#d50b4cbf3d05e3d3fe7d6f078a9719f90ca01e5f

Doesn't Work(crashes):
#008cfd1f8657c0e266a7a741920d7e9f7e187baa

To clarify both of the builds from these commits will crash with a Core Dump if started from the command line(terminal window) with:

Could not create GBM EGL display: EGL_NOT_INITIALIZED. Aborting...
(Core dump)

However, the version that works will run perfectly fine via the app icon generated in the DE launcher.
