Dear Maintainer,
* What led up to the situation?
Fresh install of obs-studio, both with an older config file and after blowing
away ~/.config/obs-studio and starting over
* What exactly did you do (or not do) that was effective (or
ineffective)?
I have tried with different versions, including the stable version. Every time
I start a stream I get a segfault:
debug: Found portal inhibitor
qt.qpa.services: Failed to register with host portal
QDBusError("org.freedesktop.portal.Error.Failed", "Could not register app ID:
