Happened right after I plugged in headphones and clicked headphone option.

Happened right after I plugged in headphones and clicked headphone option. Killed gnome tweaks, looks like menus theme settings are not working.

The headphones popup was adding in 3.20, could be an upstream bug

[Tim Lunn (darkxst)]

Thank you for taking the time to report this bug and helping to make Ubuntu better. The issue you are reporting is an upstream one and it would be nice if somebody having it could send the bug to the developers of the software by following the instructions at https://wiki.ubuntu.com/Bugs/Upstream/GNOME. If you have done so, please tell us the number of the upstream bug (or the link), so we can add a bugwatch that will inform us about its status. Thanks in advance.

Those commits look like it landed for 3.22. Will it be backported to 3.20?
