Since version 4.0.4, there is a known "bug" where if hardware acceleration is on, it will actually slow down screen redraw events. This is why scrolling is slow.

On the Samsung Galaxy III and IV, canvas would not render anything at all until we turned off hardware acceleration. Once we did canvas drawing performed well.

You can turn off hardware acceleration for your webview with this line of code in your app java file:

super.appView.setLayerType(WebView.LAYER_TYPE_SOFTWARE, null);

This may be fixed as of 4.4 (KitKat uses Chromeview rather than webview).
