Layers API seems to render incorrect position and dimensions on Mac zoom clients. Details: Example zoomConfig response: ![Screenshot 2023-05-30 at 12.55.04 PM](https://us1.discourse-cdn.com/flex016/uploads/zoomdeveloper/original/3X/e/a/ea21c27ff6ed5cfbc71c0ed2e7d60c5aec70d4d6.png) `drawParticipant` is called given the following positions: ```auto height: 552.84375 participantUUID: "10ADB150-7DDA-064D-924A-9651B65E6566" width: 781.21875 x: 43.390625 y: 282.46875 zIndex: 2 ``` This should position the participant in the middle of the following box, but as you can see the X, Y positions AND the width, height positions are off by exactly a factor of 2: ![Screenshot 2023-05-30 at 2.05.52 PM](https://us1.discourse-cdn.com/flex016/uploads/zoomdeveloper/original/3X/1/3/13b7b89291faece812c42f5e479f3801e8013aaa.jpeg) The correctly expected behavior occurs on some windows clients.

To further clarify after more testing: - Rendering positions work as would be expected on Windows 10 - On Windows 11 and Mac devices all dimensions require a factor of 2 to render correctly - There doesn’t seem to be any way to detect whether this factor of 2 is needed on a particular device, resulting in a very poor user experience ---

@MaxM , @Robert.Wallis , or anyone from Zoom team: this seems like a pretty fundamental issue with the layers API unless I’m missing something. Rendering on Windows clients seems to be inconsistent between Mac and PC clients making a nonfunctional experience for many users. Can you comment? ---

Does `window.devicePixelRatio` give you the factor of 2 you’re looking for? [Window: devicePixelRatio property - Web APIs | MDN](https://developer.mozilla.org/en-US/docs/Web/API/Window/devicePixelRatio) ---

@Robert.Wallis : genius. Yes it does. ---

Sorry to revive this for this reason but i did not have luck finding it on my own. The screenshot at the top of this post has a console with icons that label the data type. What browser / setting / extension is that? ---

Hey all I found it. It is the safari console. TY.
