When for example going through the purchase process for Apple Music, as well as other processes where you need to click through a number of links in the webview part of iTunes, NVDA does not refresh the content of the document correctly. Also, when trying to arrow through the non-refreshed content, this error is thrown:
ERROR - scriptHandler.executeScript (13:52:30):
error executing script: <bound method WebKit.script_moveByLine_back of <virtualBuffers.webKit.WebKit object at 0x04E13B50>> with gesture u'up arrow'

AttributeError: states

Alt+tabbing out of an application does not seem to fix this, a restart of NVDA is the only way I've found to render the new content.
