[Freedombox-discuss] Is there some mailing list that discusses matrix clients, specifically element desktop?

I think this outer hang-up button also left the room, not just
terminated the video call.  This was key to bypass a bug in previous
versions in which ghost users would remain in the room (with blank
screens) as I joined the room again.  But it's now gone in this latest
version 1.7.27.

Since I'm using my own server the slowest link is a 100Mb/s internal
router.  The interfaces on the FreedomBox and the compuer on which
Element runs are 1Gb/s.  Everything is connected with Ethernet cables.

Even at the atrocious uplink speed that Comcast provides, this test gives
10 fps, presumably at full resolution.  At reduced resolution, with 2
other people in the video conference I never got anything less than 15.

My local connection used to be SD at 30 fps.

I'm now thinking that there is something saved, or corrupted, in the
configuration of the room in question, not sure if on the server or the
client, that is somewow preventing a proper video startup.  The camera
icon has a slash through it and can't be "un-muted" (what is the term for
a camera?  un-videoed?)  I have no idea where the details of each room are
stored or if it's even possible to look at them or change them.  Is there
some debuggine tool or procedure to look at those details?  I've gone over
the Developer Options, the settings are all as they were originally
except for "pinned" and "layout".  Everything looks reasonable.  Like I
said before, the video is accessible to Element as proven by clicking on
the ^ next to the camera icon in the video field.  Very strange...
There is an option to send a custom event, but I have no idea what event
I could manually send (and how) to test whatever might be causing this

Given that on one other computer I don't have this problem, it's
unlikely the problem is on the server but this is an assumption.  Does
the server remember (and keep status data) about all the combinations of
machines/element clients and users?  if so, it could still be something
saved on the server.

There is one other issue, but it's not related to this problem.  In both
computers, the one that works and the one that doesn't, At the top of
the video field, when you hover the mouse on the video area there is a
field that should have the name of the room, to the left of the video
description (SD, LD, or AUD in the case of the non working computer),
but it says $roomName, literally.

Any further hints welcome.  Thanks.
