Just for posterity at this point, but: retracting my previous comment re: https://gitlab.gnome.org/GNOME/gnome-shell/-/issues/6207
It did appear fixed when the sink other than the laptop speakers was a BT (A2DP) headset. But when connected to a HDMI monitor with sound output, the quick output menu still disappears. So fix not in fedora yet, I guess.
Works here. Seems to fix the issue with disappearing sound output quick selection: https://gitlab.gnome.org/GNOME/gnome-shell/-/issues/6207 even though, as far as I can tell, the source changes: https://src.fedoraproject.org/rpms/gnome-shell/c/4b1465b8b3d49f8091a5b0846acd13f291772e91?branch=f37 don't include this change. Am I missing something from the changes?
Sorry to be a party pooper here, but I've hit a pretty nasty sleep regression: https://bugzilla.redhat.com/show_bug.cgi?id=2050036
S3 sleep as a workaround has its own issues on this laptop.
There's also an apparent (so far temporary/insantaneous) display glitch but hard to quantify.
Causes a couple of strange regressions:
Firefox on Wayland: Clicking on url bar, backspacing over part of it then pasting (e.g. a url parameter) freezes firefox, requires kill to exit. Slack flatpak: Unresponsive to quitting via ctrl-Q, requires kill or flatpak kill
Both of these issues consistently disappear after distro-sync back to 3.38.5-1.
