java - WebView clicks are not accurate

Question

I found a nice class for a dialog containing a WebView. The problem is, that every click in the dialog is somehow moved left. If I click on the right-top edge of the screen, it shows that the click was somewhere in the middle-top of the screen. I tried letting it zoom, but no luck. Can anyone address the problem?

PS: There is a repeating log message which might be related:
