Description

Chromium 117 and above uses Windows.Gaming.Input, which states

Remarks

A Windows application must have focus to receive input from a controller.

This is not useful, as users will have the game focused, not OBS.

Issue raised with Chromium: https://issues.chromium.org/issues/392661398
Original commit that introduced the change:
https://chromiumdash.appspot.com/commit/aeb76145fe766a359f2e2b7432c207cc135113b6

The mentioned flag is set to never expire, so should be available indefinitely.

Ideally, Microsoft should update this API to match the previous (XInput) behaviour, or provide a flag to set the focus policy, which is provided by the IGameInput API. Until then, we will disable WGI.

Motivation and Context

Ultimately, this is a regression. Multiple users have reported being unable to use Gamepad Viewer when using Windows 11 and OBS 31. This is a very common use case of displaying controller inputs on stream.

How Has This Been Tested?

• Launch OBS on Windows 11
• Add a browser source pointing to https://hardwaretester.com/gamepad
• Push buttons
• Unfocus OBS window
• Push more buttons
