Qutebrowser: Screenshare not working

[orangecms]

Version info:

qutebrowser v1.13.1
Git commit: 
Backend: QtWebEngine (Chromium 80.0.3987.163)
Qt: 5.15.1

Does the bug happen if you start with --temp-basedir?:

Yes.

Description

When attempting screenshare - tried with Jitsi -, qutebrowser prompts to accept, but after accepting, only errors with the following message in stdout:

[1902764:1902764:1010/224849.652974:ERROR:pulse_util.cc(300)] pa_operation is nullptr.

How to reproduce

Go to https://meet.jit.si/qutebrowser4ever and use the second button in the bottom left (appearing on hover) to attempt sharing the screen.

I can reproduce, but the same happens in Falkon as well - so probably a QtWebEngine issue. I'll investigate later and report it upstream.

There were two related fixes pushed to Qt recently:

• Do not set audio device for desktop capture if audio loopback is unsupported (Ifb13bce3) · Gerrit Code Review
• Fix getDefaultScreenId on X11 (I8e513aa4) · Gerrit Code Review

With those two applied on top of the current Qt 5.15.2 branch, screen sharing works fine again with Jitsi - I hope those two patches will still make it into Qt 5.15.2 (which is due to be released in Tuesday, so it's questionable whether low-priority fixes are still accepted), but if not, they'll be in Qt 5.15.3.

Nothing more for qutebrowser to be done here, so I'm closing this - thanks for the detailed report!

Looks like Qt 5.15.2 is delayed a bit, but still, the second fix didn't make it in time. It'll be in Qt 5.15.3, which doesn't have a schedule so far.
