ERROR:shared_image_factory.cc(880)] Could not find SharedImageBackingFactory

Describe the bug

Not a bug, but there is no template for help?

I wrote a small app with the pure-python Rio framework
The app runs fine
Building it with briefcase goes smooth, error free
But, attempting to run it results in the following error:

$ briefcase run

[<myapp>] Starting app...

There's no template for help because an issue tracker isn't a discussion forum - I've migrated this issue over to Briefcase's discussion forum (there's a tab 2 over from "Issues" at the top of the page).

As for the problem you're seeing - I know nothing about the Rio framework, so I can't really offer any advice there. All the errors you're reporting seem very Rio-specific; they seem to point in the general direction of an issue creating an OpenGL graphics context, but beyond that, it's impossible to say.

That is in part because you haven't provided any reproduction code - it's impossible diagnose an error if we don't know how you've generated that error.

My suggestion would be to take this up with the Rio folks to see if they can give an indication of the cause of the problem.
