I think I'm hit with the same issue on Kubuntu 24.04 LTS with KDE Plasma 5.27.12, X11, Linux 6.11.0-29, with an AMD Radeon RX 7800 XT GPU and an HTC Vive (2017).
Steam beta with SteamVR beta 2.12.2 and earlier are fine, SteamVR beta 2.12.3 broke everything.
Let me know if I should attach a system report or anything else as well. I'm falling back to stable for now.
Same here. I tried both RADV and AMDVLK drivers.
SteamVR 2.12.3
Steam Version: 1751405894

Radeon 6700XT
Using a Valve Index
Rolling back to stable immediately fixes the issue.
@kisak-valve plz fix 🥹
Noting that 2.12.4 does not seem to have fixed this for me.
It has been a while since I used my HTC Vive Pro. So I noticed the exact same issue starting with 2.12.4. But I didn't test 2.12.3 and earlier.
Switch to stable fixed it. The only issue left is the grainy audio thing that is discussed in another issue.
Same issue. Stable sometimes throws the error, but a restart circumvents it. It persists "permanently" on 2.12.4 beta branch.

Using stable branch works also on 6.16-rc6 to workaround the fullscreen mode error

Nothing extracted yet.
Since update 2.12.3 i get the error: "Make sure your headset´s display is in fullscreen mode" (-202)
tried deleting my
steam.vrsettingsfile, so the defaults get loaded, but it does not help.Driver: amdgpu
KDE on wayland
I have a custom build kernel which patches a amdgpu issue with mode setting of the headset, which lead to a gpu freeze before on the first start of SteamVR.. However this patch is not mainline yet.
See attached System Report for details.
