 To achieve erasing, `backgroundColor | overlayColor` must be fabric objects (see **Erasing and the `clipPath`**).
 Because of this, the mixin extends `fabric.StaticCanvas`. 
 This may cause issues when resizing the canvas. You might need to resize `backgroundColor | overlayColor` as well.
+In addition, if you do not want `backgroundColor | overlayColor` to be affected by canvas transforms set canvas' `backgroundVpt | overlayVpt` property to `false`.
 
 ```js
 canvas.setOverlayColor('rgba(0,0,255,0.4)');
