App not starting on Bazzite

Immediately after installing from the Bazaar the application hang on start up before rendering a window with these errors in the terminal when run manually.I attempted to run it with and without the sandbox.

Start by reproducing the Bazaar-installed Flatpak on Bazzite with the reported `flatpak run io.github.shiftey.Desktop --no-sandbox` command, comparing sandboxed and unsandboxed launches. Use the terminal output around EGLImage, OzoneImageBacking, and GPU-process failures to investigate the startup hang. Done means the application starts and renders a window on the reported environment.
