Known Issues and Workarounds

  • When closing browser tabs or exiting browsers without calling stage.leave(), users can still appear in the session with a frozen frame or black screen for up to 10 seconds.

    Workaround: None.

  • Safari sessions intermittently appear with a black screen to users joining after a session has begun.

    Workaround: Refresh the browser and reconnect the session.

  • Safari does not recover gracefully from switching networks.

    Workaround: Refresh the browser and reconnect the session.

  • The developer console repeats an Error: UnintentionalError at StageSocket.onClose error.

    Workaround: Only one stage can be created per participant token. This error occurs when more than one Stage instance is created with the same participant token, regardless of whether the instance is on one device or multiple devices.

Safari Limitations

  • Denying a permissions prompt requires resetting the permission in Safari website settings at the OS level.
  • Safari does not natively detect all devices as effectively as Firefox or Chrome. For example, OBS Virtual Camera does not get detected.

Firefox Limitations

  • System permissions need to be enabled for Firefox to screen share. After enabling them, the user must restart Firefox for it to work correctly; otherwise, if permissions are perceived as blocked, the browser will throw a NotFoundError exception.
  • The getCapabilities method is missing. This means users cannot get the media track's resolution or aspect ratio. See this bugzilla thread.
  • Several AudioContext properties are missing; e.g., latency and channel count. This could pose a problem for advanced users who want to manipulate the audio tracks.
  • Camera feeds from getUserMedia are restricted to a 4:3 aspect ratio on MacOS. See bugzilla thread 1 and bugzilla thread 2.
  • Audio capture is not supported with getDisplayMedia. See this bugzilla thread.
  • Framerate in screen capture is suboptimal (approximately 15fps?). See this bugzilla thread.
