Description Drew Bliss 2015-07-21 20:57:13 UTC 
Dota 2 Reborn was defaulting to fullscreen spaces on Mac.  However we ran into a couple of problems where window positioning was off so we had to turn them off.

1.      When going from fullscreen back to windowed mode, the window would be on an empty space with a black background instead of on the space the game was originally opened on.
2.      When going from fullscreen back to windowed mode, the window would occasionally be off the screen.  This was observed on a MBPr going from 2880x1800 to 1440x900 borderless window.

These came from user bug reports:
https://github.com/ValveSoftware/Dota-2-Reborn/issues/127
https://github.com/ValveSoftware/Dota-2-Reborn/issues/176

We have turned off spaces in Reborn for now but Ryan mentioned trying to see if there was something in SDL that needed to be fixed.

This part might be fixed by https://hg.libsdl.org/SDL/rev/aa1321ce8425

That one reminds me of this: https://hg.libsdl.org/SDL/rev/e88af17231bd

If the recent fixes to SDL_SetWindowSize haven't fixed this, I wonder if it's caused by something similar to the problem fixed by the above commit?

The other bug ( https://github.com/ValveSoftware/Dota-2-Reborn/issues/176 ) should be fixed now by https://hg.libsdl.org/SDL/rev/77f017f7f16d ...
