Additional Information
This is by design. In order to keep performance running smoothly, we cannot optimally watch every property of a renderer to make the appropriate redraw. The developer needs to clone the renderer and reset it themselves. It is one extra line of code, but it is worth the performance savings.Workaround
Clone and reassign the renderer.
var rendererClone = layer.renderer.clone();
layer.renderer = rendererClone;
