"Failed to get system egl display" for some Flatpak applications.

Some Flatpak applications seem to crumble when attempting to achieve GPU acceleration of some kind, such as KopiaUI and Blender.

For example, when launching KopiaUI, the application seems to respond under the hood, but the UI fails to load alongside this error

I have the appropriate Nvidia runtime flatpaks installed, I'm running under Wayland (I vaguely remember this working under X11). Additionally, I had a seemingly similar issue with Anki that was resolved by disabling "Wayland windowing system", "Fallback to X11 windowing system" and enabling "D-Bus session bus", but this solution doesn't seem to work for both Blender and KopiaUI.
