Hi!

I’m wondering if you have any clues on this issue:

> [@Webcam image gets corrupted after fixed delay (+/- 15 secs)](https://devforum.zoom.us/t/webcam-image-gets-corrupted-after-fixed-delay-15-secs/99736):
>
> Browser : Chrome OS: Windows For about 15 - 20 seconds my webcam stream renders normally (quality 360p), but then suddenly the video is garbled / starts flickering. What could cause that? I’m using the webcam in the Teams, Zoom client etc and there it works fine Edit: it happens on a video-dimension-change event the webcam starts out sending 640x360 but then switches to 1280x720. I also noticed there’s a duplicate video-dimension-change event being sent

I haven’t heard back anything yet?

regards,  
Dennis

Hey @fides-it

Sorry for the late reply.

We tried to reproduce the issue you encountered and found that video flickering only occurs when two videos are overlapping in rendering.

Could you please check if you are simultaneously rendering two videos and if their coordinates are overlapping?

Thanks  
Vic

Hi Vic, thanks for the hint. I will go through the code, maybe there’s some race condition.
