After i read ```zrender``` source code, i found how to trigger this problem in my case; First the ```zrender``` [src/config.ts](https://github.com/ecomfe/zrender/blob/master/src/config.ts) portion code: ```ts let dpr = 1; // If in browser environment if (typeof window !== 'undefined') { dpr = Math.max(window.devicePixelRatio || ((window.screen as any).deviceXDPI / (window.screen as any).logicalXDPI) || 1, 1); } ``` As you can see, ```zrender``` use ```window.devicePixelRatio ``` to set pixel almost any time in today browser if you don't config this, and my case is: First i displayed my webpage on a low pixel screen(1PX), and then i dragged the browser to mac screen(2PX), so i found this problem. So it's okay for me. Just for sharing my case. ---------------------------------------------------------------- This is an automated message from the Apache Git Service.
