This is a crash inside android GL code, not webview. Nothing much webview can do.

Hello 
As responsible for this App we really have Issues with several Clients of ours. Can you give us an update on this bug?
Kind regards

As per comment 3, this is a crash inside Android's own hardware UI rendering code; it's not a WebView crash, so we can't really do anything about it.
