OBS crashes when selecting a screen / window to capture

Support Software & Applications
1

During the last or second-to-last snapshot of Manjaro, OBS Studio seems to have been broken and no longer usable for recording and streaming. When I attempt to add a screen capture device (pipewire) OBS crashes once I select either my screen or a window to capture. I tried a fresh OBS config, the moment I add a new screen capture device it crashes again. The only information I get in the console is zsh: trace trap (core dumped) obs. I use KDE / Plasma (Wayland).

Is the issue already known? When is a fix projected if so? Do I need to provide more information at this time?

Have you already tried different kernels ?

:footprints:

I usually donā€™t play with those just run the latest stable kernel with LTS / Recommended as a failsafe. If you think it helps I could try booting up kernel 6.6.65-1, as opposed to 6.12.4-1 which Iā€™m running now?

Itā€™s likely related to Pipewire or Wayland I imagine, though without more output I canā€™t know. I donā€™t compile OBS myself to debug, everything is from the Manjaro system packages. If anyone else wants to confirm this, it should thus be easy to reproduce and hopefully gather more info than I have the knowledge to, though Iā€™d be surprised if it was something unique to my setup.

You know how it works: Maybe some inxi helps :wink:

We wonā€™t know if it makes a difference unless you try it. :slight_smile:

You could also try an X11 session to see if the same occurs; this might help determine whether or not it might be strictly Wayland related.

And of course, creating a new User account to test can help determine whether it might be local configuration related.

Regards.

Thanks: Updated the main post with the output from that command. If that doesnā€™t help I can try the LTS kernel and an X11 session when I do my next restart and see which if any resolves it.

Booted kernel 6.6.65-1 and the issue persists, I know a kernel after that still worked so itā€™s likely unrelated. Even on 6.12.4-1 I no longer get the crash on the X11 session of Plasma: Unlike Wayland I need to use a different display capture input, I added one as a test and that records the screen just fine although I canā€™t even select any specific windows. So the crash is specific to Wayland and using the Pipewire input in OBS.

I tested OBS on various KDE and GNOME distributions on my machine with the following results:

  • When running on X11, the display selector does not open at all.
  • When running on Wayland, selecting a display or window causes the application to crash.

However, It worked fine on a SwayFX-based desktop environment by installing the wlroots OBS plugin.

Thanks for confirming. Can anyone find a bug report for this already open, so I know if I should poke them about it? Sadly I donā€™t have more data, and likely canā€™t compile OBS and its plugins myself just to do a GDB trace.
