Windows 10 Fullscreen glitches out

[ZoriaRPG]

Zelda Classic crashes reliably for me if I try to alt-tab out of fullscreen mode. The segfault occurs deep inside the Windows DirectDraw library (and the cause is almost certainly the (mis)use of hardware surfaces).

I have a GeForce GTX 980 Ti and Direct3D version 12.

@DarkDragon : Would you these binaries please, and inform me if it does the same thing:

1. Open the ZQuest binary, then make a blank custom quest, and save it.
2. Open the ZC binary skipping the intro screen.
3. Open the custom quest that you saved, and see if you can alt+tab safely, or if it still crashes.

The intro screen in that build, and some music stuff is still unstable, but I'd like to know if it resolves your issue otherwise. We're working on making this bastard branch stable, but it's a slow process.
