Set "window.zoomLevel" to 2 in VSCode settings. 2. Start a page with canvas. (For example vscode-pdf uses pdf-js, which uses canvas to render a page) 3. Toggle developer tools and run `window.devicePixelRatio` in the console. Screenshot: You can see the second 123 is clearer than the first one. `ZoomLevel=2`  `ZoomLevel=log(1.5,1.2)`  Problem this is causing: From what I observed, VSCode is likely using a exponential scaling `window.devicePixelRatio = power(1.2, window.zoomLevel)`. While this makes zooming intuitive, it is likely to cause roundup issue. With zoomLevel=2, devicePixelRatio is 1.44 (up to some floating r…
