Let's make the backend expect this error and turn it into a swapchain creation failure.

Would you want to update to latest? 0.3.3 is a very old version.

Perhaps, you could provide the full call stack? Also, `debug` level logging would be useful.

So your code contains a few errors that are hinted by the validation messages. gfx-rs is totally unsafe and is not in the business to fix this for you. Crashing...

In this case, it's unreachable in a valid-written application. I'd be happy to have this fixed to a `panic!` (want to make a PR?), but this isn't going to help...

> Firstly, unreachable should mark code that is actually unreachable, even with bad inputs. Ideally, yes. In our case though, this is unsafe API, so if run-time constraints are not...

actually, it turns out to require `nightly`

@GabrielMajeri no idea. Worth a try, perhaps?

I'm thinking of dropping macOS support from OpenGL completely, see #3468

These examples use `gfx_device_gl = "0.14.0"` where the latest version is ~~`0.20.0`, which is quite ahead~~ (edit: I was thinking of `gfx_window_glutin`. GL backend is now at [0.15.0](https://crates.io/crates/gfx_device_gl/0.15.0)). Please try...
