WebView and Hardware acceleration

WebView does not work really well with hardware acceleration (available since Honeycomb / 3.0).
To avoid this issue you can deactivate hardware acceleration in your manifest (for the all app or just the activity where you have your webview).
You can do it programmaticaly too like this :

//honeycomb (3.0) and higher
if (Build.VERSION.SDK_INT >= 11)
        webview.setLayerType(View.LAYER_TYPE_SOFTWARE, null);
