Google Chrome {dev,beta,stable} and Chromium crash on Desktop Sharing on xdpw-git #205

kriive · 2022-05-04T13:46:53Z

I am on Arch Linux. I have installed xdpw via the AUR package xdg-desktop-portal-wlr-git. The issue seems to disappear if I install the xdg-desktop-portal-wlr release (on pacman).

Using the latest Firefox I can share my desktop without issues (using https://mozilla.github.io/webrtc-landing/gum_test.html).

Different story when trying the same on Chromium-based browsers.
I've tried with:

Google Chrome 103.0.5028.0 dev,
Google Chrome 101.0.4951.54 stable
Google Chrome 102.0.5005.27 beta
Chromium 101.0.4951.54 Arch Linux
with the same result:

I attach the /lib64/xdg-desktop-portal-wlr -l DEBUG -r output here.

Let me know if you need other info or debug stuff.

The text was updated successfully, but these errors were encountered:

@grulja: This looks to my like renegotiation is tripping sth. in chromium.

columbarius · 2022-05-04T15:24:24Z

@kriive I can confirm this happening with chromium native and with the flatpak version.
Can you please check if OBS is working? You need to build from master or use the version from flathub-beta.

kriive · 2022-05-04T15:51:07Z

I can confirm OBS (from master, with -DENABLE_BROWSER=OFF -DENABLE_AJA=OFF -DENABLE_VLC=OFF) PipeWire capture is working.

On my system I don't get any crashes in 101.0.4951.54 (Official Build) Arch Linux (64-bit) but the shared image is corrupted. My graphics card (RX570) does not support explicit modifiers. There is no problem in OBS. Firefox does not support DMABUF screen sharing. Running with RADEON_DEBUG=nodcc did not fix the issue.

Edit: Forcing GBM_BO_USE_LINEAR fixes the issue.

columbarius · 2022-05-04T22:30:57Z

Edit: Forcing GBM_BO_USE_LINEAR fixes the issue.

@mahkoh You only have one gpu and the image was still corrupt without the force_mod_linear option?
Didn't know that can happen.

mahkoh · 2022-05-04T22:32:16Z

You only have one gpu and the image was still corrupt without the force_mod_linear option?

Correct.

I'm trying to reproduce in Sway with latest xdg-desktop-portal-wlr from git, but it doesn't even get to settle the format:

and it keeps repeating last two lines. This is with NVIDIA proprietary driver.

Edit: same happens with OBS studio

grulja · 2022-05-05T09:12:10Z

@columbarius I see that xdg-desktop-portal-wlr uses the first render node it can find, but that doesn't necessarily be the one used by the compositor. I had same issue in WebRTC, where I used the first render node, but DMA-BUFs provided to me might be created by a different one. This will be case in multi-GPU setup, like I have for example with Intel + Nvidia.

See https://webrtc-review.googlesource.com/c/src/+/250661 for reference.

And indeed, using the other render node makes it to finally settle on the format and reproduce the issue. I will keep investigating now on my (WebRTC) side.

grulja · 2022-05-05T13:15:09Z

The crash should be fixed with flathub/org.chromium.Chromium#228. There should be a test build available soon.

columbarius · 2022-05-05T16:23:22Z

@grulja Can you please check if #207 selects the right device?

grulja · 2022-05-06T10:50:08Z

@grulja Can you please check if #207 selects the right device?

I will, but I might not have time to test it today so it will have to wait until the next week.

grulja · 2022-05-10T13:10:19Z

@grulja Can you please check if #207 selects the right device?
It does.

Without #207: xdpw: Using render node /dev/dri/renderD129
With #207: xdpw: Using render node /dev/dri/renderD128

columbarius · 2022-05-10T14:22:16Z

Great!. Thanks for testing.

columbarius · 2022-06-01T18:20:39Z

@kriive I tested xdpw master with current chromium on flatpack and it worked. Can we close this?

sentriz · 2022-06-01T18:56:31Z

all works for me too now with ungoogled-chromium/chromium/chrome flatpak 👍👍

kriive · 2022-06-02T05:53:59Z

Yes, of course! Thanks to everyone involved in the fix!
