WGI input becomes unresponsive if you click away from Cemu
In short, if you set up your input device with the WGI input, load a game and click on something else than cemu while emulating the controller comes unresponsive.
Introduced in the build that introduced WGI inputs (1.22.9), still true too 1.22.11b
Open a game in cemu with the WGI input configured and in use, click outside of cemu or something in a different software, like your web browser and the inputs are no longer responsive to Cemu.
As soon as you click on the Cemu window again the input device becomes responsive to Cemu again.
