1.9.0 - Video thumbnail refresh issue after activating video

Description
When joining a meeting (with at least one participant already in) with the Web SDK 1.9.0, we noticed than the joiner participant video thumbnail is not showing properly when video is activated right after joining the meeting.
Please check my screenshot below, as you can see, on the left you have the instructor participant (host) who joined first, and on the right a client participant (non host) who joined after the instructor.
The client video thumbnail is not showing after activating the video.
Switching to gallery mode and then back to speaker mode solve the issue, so it seems to be a UI refresh issue.

Which version?
1.9.0

To Reproduce(If applicable)
Steps to reproduce the behavior:

  1. Join a zoom meeting as host with web sdk, and activate video & audio after joining
  2. join a zoom meeting as non host with web sdk, and activate video & audio after joining
  3. On the non host participant, your own video thumbnail is not working due to probably a refresh bug on the UI
  4. On the non host participant, clicking on the gallery mode and then back to the viewer mode, the thumbnail video is fixed on the non host participant.

Device (please complete the following information):

  • Device: Desktop Linux, Window, MacOs

This is a blocker issue for us (as our customers may not know how to fix that bug by themselves by switching the view modes), so we are not going to update to 1.9.0 before this can be fixed.

Can you give us feedback on it about your findings and potential SDK version with a fix?

Thank you !

we’re experienced the same issue with the sdk v1.9.0. After switching the view mode (f.ex. to gallery view) the preview is working as expected.

This is also happening time to time when a participant deactivate the video.
The thumbnail still show that participant on other’s screen but with a frozen image instead of showing no video with the deactivated sign.
It can be fixed by switching view mode so i guess it’s the same bug, or similar one.

Our organization has also experienced this behavior since updating to 1.9.0. As other posters noted, switching to Gallery view resolves the issue.

Thank you for raising this with us. We are looking into this (CS-3013).

Thanks,

We are also experiencing this issue after the upgrade to 1.9.0. Switching to gallery view resolves it - we also noticed that sharing screen would trigger the video to start as well.

Hey @erichhansen,

I’m sorry to hear you seem to be encountering this bug as well. Thank you for your input and for sharing the workaround that worked for you. We’ll be sure to update you here when we have more information.

Thanks,
Max
