2 years ago Thanks for the ping. i don't know what could be causing this crash. __memmove_avx_unaligned_erms is usually a general memory corruption - either unintialized or freed memory. So this indeed looks like a use-after-free.

2 years ago After thinking about where the segfault come from: https://github.com/obsproject/obs-studio/blob/b92e941b4f24d33b2b2677bcc005492d493ef606/plugins/linux-capture/pipewire.c#L518-L521 I found a workaround, which is to uncheck Show Cursor in the Pipewire screen capture properties window. Instead of OBS crashing within several seconds, now its stable for at least 10 minutes

2 years ago @minecraft2048 Please keep in mind that these crashes can be quite random. At least for me, they could happen in the first 5 minutes, or only after 3+ hours of streaming/recording.
GeorgesStavracas
commented
2 years ago Given that the only thing in common between all these reports is that they all use KDE, I'm starting to think the KDE implementation is sending a bogus cursor through PipeWire. That would be the only reasonable explanation. PipeWire itself doesn't touch the contents of the cursor, only OBS Studio, so we end up triggering the crash.

HI, I don't know much about the implementation of cursor support in KWin. This was implemented by @apol and the code is here.

2 years ago having the same issue here. Distro: Arch DE: Gnome Pipewire: yes

in some cases it froze the whole system.

2 years ago @Magi-KS yes, your backtrace seems completely different than the other ones shared here. Could you please open another issue with that? Make sure to fill in the template too.

2 years ago A crash in x264 is almost always due a broken system (and that you have symbols for it is highly suspect). Please use support in that case.

2 years ago Well that's also a perfect recipe for breaking x264. Please use one https://obsproject.com/help probably our discord or forums.

6 months ago Is this still occurring with modern OBS Studio (30.1.1+) and a modern environment+dependencies? This doesn't seem like it was our bug to fix, and there have been plenty of changes/fixes in KWin for cursor handling in the meantime. https://invent.kde.org/plasma/kwin/-/commits/master/src/plugins/screencast/screencaststream.cpp

Unpredictable crashes every 5 to 180 minutes
Steps to Reproduce
Anything else we should know?
I'm using:
During recent streaming sessions, I've encountered a lot of random crashes, sometimes minutes apart, sometimes after a couple hours of streaming. Running with debug symbols under gdb has revealed a segfault at plugins/linux-capture/pipewire.c:478:
Given that line 478 nullchecks the pointer before using it, I assume it must be a dangling pointer. I'm not sure where to go looking from there, though.
