New project fails to start

[jessiahr]

I am finally getting around to trying to get this project running on my machine but I'm getting some odd results. This is just the standard project after running mix scenic.new.example my_app It looks like main_viewport exits repeatedly and then floods the Logger inbox:

Am I missing something?
Enjoyed the demo at elixir conf 2018 btw!

Hi @jessiahr. There is a known issue that I need to publish the fix for. Please try pointing the scenic_driver_glfw dependency at the master version in github. If that doesn't work, let me know.

Otherwise wait a few hours as I'm hoping to get that published to hex later today.

[boydm]

Update is now on hex. Please run scenic.new again (or mix dep.update scenic_driver_glfw) and it should work.
