Pipewire screen sharing under Wayland results in black canvas with cursors

[kotatsuyaki]

NVIDIA Open GPU Kernel Modules Version

525.89.02

Does this happen with the proprietary driver (of the same version) as well?

Yes

Operating System and Version

NixOS (Nixpkgs commit 806075b)

Kernel Release

6.1.13

Hardware: GPU

NVIDIA GeForce RTX 3070

Describe the bug

When using Pipewire screen sharing on Chromium or Firefox on Wayland, the shared stream is black, with the cursor visible and moving. Here's a screenshot of it.

This bug was reported to Pipewire. All affected users are using the proprietary Nvidia driver, and the bug is reproducible with the open kernel module.

Note that while on Chromium and Firefox the results were black, I was able to record the screen with OBS Studio, so it's unclear whether this bug belongs to here.

To Reproduce

1. Open Chromium or Firefox.
2. Open any website that uses WebRTC screen sharing (tested on https://www.webrtc-experiment.com) and share the screen.
3. From the xdg-desktop-portal popup dialog, select the entire screen.

Bug Incidence

Always

Due to Nixpkgs missing the nvidia-bug-report.sh script (NixOS/nixpkgs#172739), this part is left out.

More Info

No response

Adding more info about the bug.

The bug happens when using Wayland, screen share on OBS works fine. But on WebRTC only black screen with cursor moving around.

Chrome Debug on sharing with WebRTC (when launched from the terminal):

I have the same issue. It happens only with NVidia GPU, my other PC with AMD works fine. It happens with 530 beta driver as well, both proprietary and open one.

[GrabbenD]

Same issue here!

[otacke]

Not sure if this helps, but I am in the same situation: black screen and only mouse pointer visible when sharing the screen on Wayland.

How ?

[otacke]

@ayoubedd I replaced the NVIDIA card with an ATI board ;-) I've had other trouble with NVIDIA before, so I thought it might be time for a change eventually.

[Cylon-interrogator]

I absolutely agree, Nvidia just sucks on Linux. However, I've got ton of NVidia GPUs lying around left over from 2021 crypto craze waiting for the next bull run, and I've put one of the to my secondary rig in my second home ... At least, now when they've opened the drivers, there is hope for the future ...

[ar-nadeem]

Leaving Nvidia is not a choice for me. AI, Cuda, and other software implementations of Nvidia are of great use to me. Nvidia wants nothing to do with Linux. The bare minimum drivers with billion of bugs are all they do. This might change because of Steam Deck, why wouldn't Nvidia want their GPU in the steam deck instead of AMDs? But for now, I shifted back to Windows.

Problem still occurs on 530.41.03-1

I have KDE 5.27.5-1 and kwin 5.27.5-2 and have partially (can share windows, but not whole screen) made screen sharing working by:

1. Install xwaylandvideobridge. You need it to stream wayland windows to x11 apps (like to screenshare in discord or telegram, you dont need it for wayland window to wayland app streaming)
2. Add following string to ~/.profile file to use glx instead of egl backend.

#O2: OpenGL 2 backend
#O2ES: OpenGL ES 2 backend (since 5.5)
export KWIN_COMPOSE=O2

3. (optional) Remove if set --use-gl=egl flag from browser launch flags to fix GPU acceleration.

I think you can fix it for other window manager if you somehow make make them not work with egl

I think recent NVIDIA driver have somehow broke OpenGL ES because if i fetch info about it via eglinfo -B i receive:

GBM platform:
EGL API version: 1.5
EGL vendor string: NVIDIA
EGL version string: 1.5
EGL client APIs: OpenGL_ES OpenGL

No changes in telegram screen sharing on KDE Plasma 5.27.4 and 5.27.5, NVIDIA dkms 530.41.03-4, RTX 3060. But I experience same bug with eglinfo and glxinfo commands.

[ar-nadeem]

Soo still not fixed? Are we sure the problem is with the drivers not playing nice with Wayland screen-sharing policies?
