Emulator

Game Name?

Virtual Console or WiiWare titles

What's the problem? Describe what went wrong.

I never had fullscreen enabled by default on Dolphin, until my father started playing Wind Waker. So instead of making him press difficult hotkeys every time, I had "Use Fullscreen" checked for him. But he decided to play older games, like Alex Kidd, and every time he booted it, it crashed. I did some testing and saw that actually, every VC or WiiWare game I have, crashes Dolphin with "Use Fullscreen" enabled by default. Borderless fullscreen also crash. Booting a game windowed and going fullscreen afterwards works normally. Render to main window, and having "Use Fullscreen" checked also works.

Since my GPU is old, I can't use OpenGL or other backends.

What steps will reproduce the problem?

1. Choosing Direct3D 11 and checking "Use Fullscreen"
2. Booting a VC or WiiWare game
3. Dolphin crashes in a black screen, can only exit by forcing through task manager

Which versions of Dolphin did you test on? Does using an older version of Dolphin solve your issue? If yes, which versions of Dolphin used to work?

I don't know why this issue hasn't been caught earlier, but it started on 5.0-76 (VideoBackends: Merge backend initialization and shutdown - PR #3510). There's a comment in the PR about this issue, if it had been checked XD (I guess):

This PR crashes all WII games (gamecube games work) when used on D3D 11 regular fullscreen mode. Just a blackscreen and full lockup that requires a force close with task manager. D3D 12 and Open GL work perfectly. It also works with render to main.
I did not check Virtual game and WII ware to see if they were affected too.

On 5.0-72, and OpenGL (I can't test other backends), it works as it should.

What are your PC specifications? (CPU, GPU, Operating System, more)

Windows 8.1 Pro 64 bit
AMD Athlon II x2 240 2.8Ghz
5GB RAM
GeForce 9600GT 1GB

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

Nothing that I could think of.
