This should actually be fixed by #476. GLXBadDrawable happens when you try to render to a destroyed window, and the associated error messages aren't relevant, since those are just the first checks to catch the error. Looking at your issue report on Amethyst, the reason it started after a glutin update was likely due to #416 being included in that.

I've had this same general problem in my own gfx apps. I was handling Closed by stopping the loop at the end of the iteration rather than immediately, which I imagine is a common pattern. After #416, that means you'll always attempt to do one render after the window's already been destroyed. The reason this doesn't come up when closing with escape is because escape doesn't actually destroy the window, you just safely exit the loop and then the window is ultimately dropped.

In the short term, I don't recommend doing anything to fix this in Amethyst, since you'd just end up reverting that once CloseRequested/Destroyed lands in a release.
