Expected Behavior
OBS not crashing when adding a Browser Source to the Scene.
Current Behavior
OBS crashes without any stacktraces (also when launched in the verbose mode)
Steps to Reproduce
- Launch OBS
- Add Browser Source to Scene
- OBS Crashes
Anything else we should know?
I'm using the OBS Flatpak Package from Flathub
I cannot reproduce this on Xorg:
So Wayland-specific, perhaps?
If you can, try getting a stack trace.

Not getting any Stacktraces when trying to run with gdb. Is there some libcef debug package for flatpak?
Is there some libcef debug package for flatpak?
It seems that CEF is downloaded from OBS servers, but it's pre-built and has no debug symbols:
https://github.com/obsproject/obs-studio/blob/122e864c38e9abfc94a2e381580278a3a44eda5c/CI/flatpak/com.obsproject.Studio.json#L398
It's not clear to me if the OBS team provide the symbols for download elsewhere, so I believe you'll have to wait for a response from the team.
When Building the OBS Package from source, it works without any issues. There I noticed that the Build Instructions are using the "cef_binary_4638" instead of the "cef_binary_5060". But it also isn't crashing when using the 5060 Cef Binary ... only when using the flatpak package ...
I confirm i, also, have this issue, on fedora 37, with flatpak.
Here's the log of crash, i was thinking first it came from v4l2loopback, but it's still do that after a modprobe -r v4l2loopback so i guess no ?
Here the logs during the crash :

When forcing OBS to run in X11 Mode by disabling the Wayland socket and adding QT_QPA_PLATFORM=xcb to the environment variables, it works without any issues ...
(Can be easily done with Flatseal)
It seems that the problem only occurs in Wayland when using an AMD GPU (maybe only AMD Polaris GPUs?). The browser source works fine on my laptop with integrated Intel graphics.
Checking with our team, we haven't been able to reproduce this on our end, so we aren't sure what's going on and it might be something specific to your environment. Since we cannot reproduce, there is not much we can do to further help identify this, but there is something obviously crashing here, so we will leave it open for now.
We don't distribute the CEF symbols because they're several gigabytes in size and it's not practical, but I do believe we store them internally for cases like this. I think @pkviet should have them.
Browser source will also crash on my rock5b, an arm SBC with rk3588 soc running with panfork GPU driver. I will test more arm SBCs with panfrost driver and report here.
Also seeing this, not using AMD GPU.

Unfortunately can't get a useful stacktrace of obs because I don't have the debug symbols.
OBS crashes even if the browser source is in another scene. Disabling wayland via Flatseal allows you to start OBS again, but it won't be able to capture anything through Pipewire
