Is this only after the libx11 update?

Had not tried obs-studio pre libx11-1.6.4-1.
I just tested it again on my thinkpad after downgrading to libx11-1.6.3-1 and it still segfaulted as described.

Does recording work for you? And which DE/WM are you using?

Just tried, it segfaults when attempting to record as well. I'm using i3.

I see "Couldn't initialize muxer" in the console output before it crashes when attempting to record. I also did a backtrace with gdb for you:

Hope that info helps.

Here's the upstream issue: https://obsproject.com/mantis/view.php?id=640

I've found that running a tray "fixes" the issue. So run "trayer" for example and it doesn't crash. Not a solution but a workaround.

I see that Jim has fixed it upstream as well. Will use your workaround until the next stable obs release; thanks :)
