The new Steam controller doesn't register input from Dolphin emulator when games are launched through ES-DE
It's weird, I always use ES-DE to launch emulated games on my Steam Deck in Game Mode, this works fine for all emulators when I use the deck as a handheld. And all emulators (Eden, Duckstation, Cemu, etc.) also work fine when I have the deck docked and use the new Steam controller. But Dolphin doesn't, the new Steam controller doesn't register any input when I launch a Gamecube or Wii game through ES-DE (I have custom controller layouts for all my emulators).
Strange thing is that when I lauch Dolphin directly in Game Mode (I added the emu as a non-steam game to the library), then the controller works as it should, all inputs are registered as I defined them in the Dolphin controller layout.
Why does the controller refuses to work with Dolphin when launching games through ES-DE?
