I’m digging into a bug in the handling of external monitors in GLFW 3.x (taken 2 days ago from the Git repo head).
First, I’m getting all available monitors with glfwGetMonitors. The info I’m getting is:
Monitor 0, res: 1920x1080 // This is the external monitor Monitor 1, res: 1280x800 // Laptop monitor
I’ve configured OSX to setup the external monitor as the primary one, so what GLFW is returning here makes sense.
Now, if I try creating a fullscreen window with that data, GLFW just goes nuts. If I use monitor0, it just barfs the error in the topic title, and fails to create the window. If I use monitor1 it does create a window, but it does so on the external monitor instead of the laptop one as I requested.
Finally, after configuring OSX to setup the laptop screen as the main monitor I get this info:
Monitor 0, res: 1280x800 Monitor 1, res: 1920x1080
Again, this makes sense.
But now the behavior is reversed: selecting monitor0 creates a window on the laptop screen (as it should), but if I try monitor1 it just shows the NSMapGet error and fails.
I have no problems with windowed mode, and everything works fine if I don’t plug in the external monitor.
Hope this helps!
