Emulator

I didn't open the original issue, but I had it "starred" and saw that the original creator has been unresponsive for nearly a year now. I understood what they meant and have run into the same problem, so I figured I'd quickly clarify.

Game Name?
Any

Game ID?
Any

What's the problem? Describe what went wrong in few words.
For example: In Wii games where the Wii aspect ratio is explicitly set to 16:9 (or it's forced in the graphics options with Wii or GameCube), "Auto adjust Window Size" still resizes to what is roughly a 4:3 window.

What did you expect to happen instead?
I expect the window aspect ratio to be 16:9 if Force Aspect Ratio or if Wii Aspect Ratio is set to it.

What steps will reproduce the problem?

1. Start any Wii game with 16:9 set in the Wii options (or GameCube with Force Aspect Ratio)
2. Enable "Auto adjust Window Size" in the graphics options

Dolphin 3.5 and 3.5-367 are old versions of Dolphin that have
known issues and bugs, so don't report issues about them and test the
latest Dolphin version first.
Which versions of Dolphin did you test on?
4.0-3453

Does using an older version of Dolphin solve your issue? If yes, which
versions of Dolphin used to work?
No.

What are your PC specifications? (including, but not limited to: Operating
System, CPU and GPU)
For good measure: Windows 8.1 x64, AMD FX6300, AMD R7 265, 8GB DDR3 RAM

Is there any other relevant information? (e.g. logs, screenshots,
configuration files)
Excuse my use of dropbox; it was the most convenient. I'll re-upload if I absolutely must.
