"Share your screen" dialog in video room stays stuck on loading animation for sources (Linux, Manjaro XFCE)

Steps to reproduce

1. Create or enter a video room.
   • To do this, you will first need labs flag feature_video_rooms to be true and be running Element version 1.10.9 or later. For reference, this issue was encountered on Element 1.10.13
2. Join the video call with the join button.
3. Hover over the video panel until the control GUI appears.
4. Click the button which has tooltip “Start / Stop sharing your screen”
5. Navigate back and forth between the “Your entire screen” and “Application window” tabs, waiting at least 10 seconds on each tab.

Outcome

Expected behavior:

• After fewer than 10 seconds of waiting, a list of screens is expected to be visible and interactive on the “Your entire screen” tab of the “Share your screen” dialog.
• After fewer than 10 seconds of waiting, a list of application windows is expected to be visible and interactive on the “Application window” tab of the “Share your screen” dialog.

Observed behavior:

• After more than 10 seconds of waiting, the loading animation continues playing, with no list of screens visible or interactive on the “Your entire screen” tab of the “Share your screen” dialog.
• After more than 10 seconds of waiting, the loading animation continues playing, with no list of application windows visible or interactive on the “Application window” tab of the “Share your screen” dialog.

Additional information:

• Running the Jitsi Widget in Chromium on the same system and sharing screen from there immediately populates the lists of screens and application windows when starting a screen-share.

The plan for video rooms is to move them to Element Call as soon as it is ready so that will remedy this. Video rooms are still under active development as per the labs flag description.

Okay. Thanks.

Video rooms are still under active development as per the labs flag description.

That is exactly why I reported this issue, as I expect issues are expected to be reported for features which are exposed for testing. I understand the rationale for closing it though.

By the way, I’m very happy that voice rooms are being added to Element, but I’m not sure about where to read about the intended design. For example, I really hope the voice/video room joining behavior changes eventually to leave the most recent non-voice/video room selected and just add the user to an indented visible list of users inside the voice/video room, and have them join with audio only without confirmation. This would match Discord’s intuitive voice channel joining behavior. I don’t know where I could research whether that’s planned, and whether I should open an issue ticket here proposing that design change, if it’s not planned. Is there a central public place where specific approved and planned feature design specifications like this are documented?
