Emulator

i can reproduce this consistently

I'm only just running Dolphin on my Steam Deck 2022 LCD model to trigger the bug.
No software or anything else is run.
Mayve it's related to the model being used?

Tested the preview version of 3.5.8. Still occurs on my launch deck.

Can also reproduce on a August 2022 Steam Deck LCD 512GB, I have never modified the device and I am using the Flatpak build from the Discover store. It also did a weird thing where my inputs are read in Steam's desktop controller layout because the B and Start button would start behaving like the Esc key.

Same issue here, launch model Steam Deck.

Same issue here, Dolphin Version 5.0-20247 (via Emudeck), SteamOS 3.5.7, LCD Deck bought 8/2022.

Please note that also the "A" button is affected, so even if you successfully navigate with the left thumbstick instead of the dpad, everything is confirmed twice and submenus are unavailable.

I too have this problem on my launch model 512 GB Steam Deck on Steam OS 3.5.7 with Dolphin 5.0-20347 (flatpak)
Navigating menus in Gaming Mode is nearly impossible without the built-in mouse. The only way to resolve it is a reboot after playing any games on Dolphin.

Please add the option to disable whatever is causing this in the settings, we already have a way to make gryo stay on in steam input. It is rediculous that this "feature" is making most decks unable to use dolphin and there has been no workaround.

This is still happening in the latest nightly appimage and the flatpak. It's like the default steam deck keyboard binds are locked ON when dolphin opens. When launched through steam it will still recognize controller inputs, but the keyboard layout stays locked on with it. After quitting dolphin, the controller stays in this state and makes every input send both signals at the same time. Restarting steam fixes this, but there's no way that I know of to make the steam deck controller work on the LCD model atm in dolphin :{

Everyone who has this issue, we need to check something. Go into desktop mode and run Konsole, and type "lsusb -d 28de:1205 -v" (lower case L btw) and press enter. This will give you the information on the "Steam Controller" for the deck. Now look for "bcdDevice" (NOT bcdUSB or anything else) and you'll see a number beside it. Post that number here, and say again that you have encountered the issue in this issue report. Something like:

2022 Launch Steam Deck LCD
bcdDevice 2.00
Has the issue

If we can get a bunch of reports like this we may be able to tie the issue to a specific piece of hardware and possibly report a bug to Valve.

2022 Launch Steam Deck LCD
bcdDevice 2.00
Has the issue

2022 Launch Steam Deck LCD
bcdDevice 1.00
Has the issue

Hi, author of the patch in question here. Would anybody be willing to provide either remote (i.e. SSH) access or in-meatspace access (London or commuter belt, UK) to a Deck exhibiting the problem? It's very difficult to debug this issue without the hardware in question.

If you can, please test if 5.0-20923 / c3b8aa1fe582d9798939a1975e559ad4a69c3f02 fixes the problem.

Tried a self compiled build, and it looks like 5.0-20923 / c3b8aa1fe582d9798939a1975e559ad4a69c3f02 did indeed fix the problem.
Did notice something that, after opening the controller options once, I can't open the controller options again until I close and reopen Dolphin, but im unsure of it's related to the fix.

Please contact me on discord, my handle is "superboo07". I have a deck with the issue and am happy to give ssh access or whatever is needed to help with patching.

Thank you so much, is there an estimate on when this update will be pushed to the flatpak

Any Flatpak version (and any other Linux builds) are not officially maintained versions of Dolphin. Please ask the maintainer of your Flatpak.
