Ok here's an issue I'm running into every other day, but it's hard to reproduce. What happens is that sometimes when my game switches from fullscreen to windowed mode the LÖVE window disappears from the screen.
The game still is running - I can hear the sounds and see the terminal output and the Icon is still in the Dock - but there's no way to get the window to come back. Alt-Tabbing to the app for example doesn't do anything.
I'm pretty sure that it's not an issue with my code because I'm not doing anything fancy besides
love.window.setFullscreen( not love.window.getFullscreen() )
The problem is that it doesn't happen every time. Maybe out of the 50 times I start my game it happens once.
I'm on mac OS 10.11.6.
