I've had the exact same issue for months. Unable to sign in to multiple games or chat with controller because of this issue. Linux Mint 22 (Ubuntu 24.04)
Kernel: 6.8.0-45
DE: XFCE

Edit: Still no change after multiple Beta client updates. 11-14-24

So it's not Arch specific nor Gnome specific, good to know.
I forgot to mention that I have been using x11 but I can test it on wayland.

I tried a few Wayland-legible forks of Proton and reproduced the same issue, so it's not just you.
I suppose https://github.com/ValveSoftware/steam-for-linux/issues/11236 is the issue you're experiencing as well?

I think I used to have a simillar issue quite a long time ago but right now it's only this (at least in relation to a keyboard input)

For me this only happens while using "big picture overlay" (so only when a game is running)
exact same issue some keys act as arrow keys T⬇️ R ➡️ and O⬆️

just being in big picture itself without a game running, the keyboard (physical or virtual) works fine

UPDATE: if running steam bigpicture with gamescope the "big picture overlay" behaves normally and keys work and they should:

• native

gamescope -f -e -- steam -gamepadui

• flatpak

gamescope -f -e -- flatpak run com.valvesoftware.Steam -gamepadui

could have the same effect if running the game with parameter gamescope -f -e %command%

But, how?

@Neubulae what is it, what are you having trouble with?

@Neubulae what is it, what are you having trouble with?

Oh I didn't mean to reply it, I wanted to ask how this workaround "works" but nevertheless this should be answered by Valve, not average users.
Besides that, simply running the game inside gamescope doesn't fix this issue for me.
I am simply shocked and a bit confused by why scoping Steam within Gamescope "fixes" this issue, for that I wanted an explanation. Needless to say your post provided a lot of help at least for me, but this issue still makes me feel nervous.

Marking myself as affected by this as well, though tagging in a comment to state that this isn't Arch-specific, despite the Distro Family tag. I'm currently on Ubuntu Noble/24.04 with the deb installation and experiencing this exact same behavior.

Same issue as https://github.com/ValveSoftware/steam-for-linux/issues/11236 and https://github.com/ValveSoftware/steam-for-linux/issues/11158

This still seems to happen.

One clue could be that system installed Steam has the bug, but the Flatpak version works fine. On Pop!_OS 24.04, Wayland, Cosmic desktop, AMD GPU.

EDIT: It seems I was wrong, Both the system installed Steam and the Flatpak version has the same bug. I tried two games, Baldurs Gate 3 and Factorio. The overlay virtual on-screen keyboard bug is present with BG3 both in the system installed Steam and in the Flatpak version. But the bug is not present with Factorio.

EDIT 2: The search field in Big Picture mode, without any game running: The virtual keyboard works, including the r, t and o buttons.

EDIT 3: Same bug with Valheim. Also while a game that triggers this problem is running, the search text boxes in the Steam store are also affected while one of those games are running, but not when they are stopped.

EDIT 4: Same bug with a physical keyboard while one of those games are running with the Big Picture overlay active. The problem seems to go away if the overlay is disabled.

Still having this issue myself. Can't even type the r t and o keys using the game's in game keyboard. The only thing I really have to do in game is chat with friends and it's the one thing I can't do with big picture mode lol
