Zoom Web SDK rendering bug on Safari browsers for own video display

[carlito]

There is a rendering bug in the the Web SDK for Safari Browsers affecting the users own picture display. The self video running on the safari browser is rendering incorrectly and not within the bounds of the video tile. The video displays normal on other users screen, but will not display correctly for themselves. We are using SDK version 3.9.0 and component view, but have tested the same bug to be present in and up to version 3.10.0.

The lower user on the pic below has their video on, however you can see the video has not rendered in the correct place and is off the screen. This displayed correctly on the second users screen who was not using safari.

When tested on IOS mobile safari browser the video was about 20px x 20px and within the boundaries of the tile. It was visible unlike the example below but not rendering the correct size.

This issue occurs only on safari with the new gallery mode when sharedarraybuffer is not used. Recycling the video on and off several times will eventually get the users own picture to display correctly when there are multiple users joined to the call.

This does not fix the issue when no users have joined. Below is a picture of the issue on safari when no other users have joined yet and you are the host.

I dont have an account to add a ticket, but could you contact me zoom and I can show you the bug. Its very frustrating for Safari users.
