When using fullscreen mode on glfw3 on macOS, it seems like I cannot swap to other apps or enter mission control. Is this the expected behaviour? If yes, is there a plan to change this?

Unfortunately, there’s another fullscreen issue… I have compiled the app with OS-X 10.9 and there it works fine.

But if I start the app on a 2nd testmac with OS-X 10.6, the screen is just white. (window mode works, though) Inserting -mmacosx-version-min=10.6 into cmake for the compiler and linker flags does not help.

Any hints how to fix this?
