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.

[nikzasel]

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?

The problem in https://github.com/NVIDIA/open-gpu-kernel-modules/issues/467#issuecomment-1544340511 still occurs for me with version 535.54.03.

I suspect this may be the cause of a crash I'm getting when launching a different program, but it's hard for me to say for sure.

Is this Fixed ? This is the only thing stopping me from shifting to Linux from Windows.

I fixed all of my Wayland- and hardware acceleration issues by switching my GPU to AMD @ar-nadeem Don't bother using hardware which gets minimal support on Linux

That's just like when you ask how to fix an issue with a game under Linux and someone replies: "Dude, just use Windows!" ... Why haven't we thought of that, I wonder ... Anyhow, I don't think that's very helpful answer. Yes, everybody knows that Nvidia (still!) sucks under Linux, although it has improved a lot during last year (as corroborated by various Linux users). Some people still prefer or need to use Nvidia for various reasons - better ray tracing support, CUDA, DLSS ... I personally use it on my secondary rig (my primary PC has RX 6700XT inside) because, I've got a lot of Nvidia GPUs lying around from 2021 crypto bull run ... also, there is not that many laptops with AMD GPUs, not even in those that are supposed to be tailored to Linux, like Tuxedo, so there is that ...

[GrabbenD]

Dude, just use Windows

Not a fair comparison.. We can't fix issues in Windows We can't fix issues with hardware behind closed binary blobs

everybody knows that Nvidia (still!) sucks although it has improved a lot during last year (as corroborated by various Linux users).

Yes, they have sucked for the past decade We shouldn't expect too much from a multi billion dollar comapny small company like NVDIA though 🙂

Don't support evil companies Vote with your wallet

Do you know how multi billion dollar companies stay billion dollar companies? They don't throw money into things that they think won't bring them money back.

Reality is that the crowd running Nvidia on Linux, followed by the crowd that runs Wayland is pretty small (although steadily growing). I also dislike that they don't invest more attention into Linux but that's just company priority for you.

I fixed all of my Wayland- and hardware acceleration issues by switching my GPU to AMD

Comments like these are just unhelpful for everybody involved, it's off-topic (this comment too). Everybody here knows driver support is better on AMD (or should at least), some people can't buy another GPU (like being too poor for another GPU) or it doesn't make sense for them to switch (like people who have AI workloads).

Ideally using Wayland should be device agnostic.

But Cylon already told you this and you didn't address their strong arguments so I'll default to you not being here for a good faith discussion. Please just don't comment this, it clogs up the issue which might make a dev less interested working on this.

[ar-nadeem]

Hey, good news. I think it is fixed.

WebRTC is working fine in Firefox (both Window and Screen Sharing). I get the black screen with just a cursor in both screen and window capture in Telegram Wayland screen sharing though. I have attached the image below. (@ar-nadeem)

WebRTC in Firefox:

Telegram Desktop (rpm package) screensharing not working:

I yet have to test with other applications. But this also now works on gnome. You have to install pipewire-media-session and all other pipewire related stuff. Then reboot and it will work.

[glaeqen]

Small nitpick

You have to install pipewire-media-session and all other pipewire related stuff. Then reboot and it will work.

pipewire-media-session is not supposed to be used, it was just a demo session manager for which wireplumber is a fully featured replacement. FYI

For sway, naively adding support for DRM_FORMAT_BGR888 to xdg-desktop-portal-wlr appears to work

Ha, it looks like someone made such a change just yesterday https://github.com/emersion/xdg-desktop-portal-wlr/commit/84a9cf40fb6e5b2900c7d245a1ac8acad828a88f

So screencast with sway/wlroots ought to be working with the latest xdg-desktop-portal-wlr
