Arnold renderview window out of whack

[daschund]

For some reason, when I open Arnold RenderView it gives me a window where the actual render is out of the window, like you can see on the images. Doesn't matter how big I make the window, I can't see the whole render frame.

So, resetting the preferences fixed it

If you keep the old prefs, we can do a diff and maybe see what happened.
