Wpf Example crashes on Resize

[leepa]

Download latest binary release. Resize horizontally and back a few times without lifting the mouse button.

You'll crash.

This also happens when you include a new WebView in an empty WPF window. Even when no document / URL is loaded the application will crash after some window resizes.

Thanks. I think this will be fixed by some of the work that people have done to fix some coordinate mappings that were problematic in the offscreen rendereing mechanism. i am going to merge/test fixes for this during the week.

see here for example, there are a few more fixes in other forks as well:
