Emulator

Game Name?
Any.

Game ID?
Any.

What's the problem? Describe what went wrong in few words.

Doplhin freezes with black screen and stops responding when I exit any game that is running with D3D and exclusive fullscreen. The only way to exit the program is through Task Manager (and even that is inaccessible, if it isn't set to run "on top"). The hanging happens with either Esc or Alt+F4.

What did you expect to happen instead?
The game to stop running and Windows desktop to reappear.

What steps will reproduce the problem?

1. Download any Dolphin master after 4.0-6018 (last working version)
2. Optional: create portable.txt in Dolphin folder.
3. Start Dolphin and select D3D Backend
4. Choose Use Fullscreen (or access fullscreen after game has started)
5. Start any game, wait for it to run in fullscreen.
6. Try to exit the game using Esc or Alt+F4 -> black sreen + hang.

Which versions of Dolphin did you test on?

4.0-6021 and later master

Does using an older version of Dolphin solve your issue? If yes, which
versions of Dolphin used to work?

Any version before 4.0-6021.

What are your PC specifications? (including, but not limited to: Operating
System, CPU and GPU)

Windows 8.1 64bit, i5 4670S, Intel HD 4600 (latest drivers).

Is there any other relevant information? (e.g. logs, screenshots,
configuration files)

Another user @trihy verified the same issue on forum, he was using gtx970 with latest drivers.

This may not affect all users, but with my pretty basic setup this is consistent.
