**Video SDK Type and Version** _Zoom Video SDK Web. 2.2.0 onward_ **Description & Error** _I am using a canvas to render out all of the users videos using renderVideo and stopRenderVideo methods. Sometimes when a user stops their camera, a black rectangle is left where their video used to be. This has not been happening on 2.1.10 which seems to be the last stable version for me. Also, what I have noticed is that the failure rate of renderVideo being a lot higher. Sometimes when changing the dimensions there will be white overlay to where the video is supposed to be and every time the_ adjustRenderedVideoPosition method will fail saying the video isn’t rendered yet. For the code I am mostly using the code provided on your GitHub repository for videosdk-web-sample with slight changes. **How To Reproduce** Two users are in meeting, one camera off, one camera on. When the user leaves with his camera on, a black rectangle is left where his video used to be. This happens until a canvas refresh happens or dimensions change. This was not happening on 2.1.10 version. ---

> [@Ekko](#): > > Having issues with `renderVideo()` in versions after 2.1.10 — black rectangles remain when a user with camera on leaves. Also seeing white overlays and `adjustRenderedVideoPosition()` failing at times. Works fine on 2.1.10. Any fix or workaround? Hey, after version 2.1.10 I’ve been running into issues. When a user with their camera on leaves, a black box stays on the canvas. Sometimes there’s even a white overlay, and `adjustRenderedVideoPosition()` fails. Everything worked fine on 2.1.10. Any fix for this? ---
