Since updating to 1.5 the background images (featured images for page) in the text areas on the landing page no longer adapt to size of page but form a mosaic. Is this deliberate or a bug? If deliberate is it possible to return to previous situation?
Are you using Safari? On Safari the fixed positioning is disabled as a workaround because the browser is not capable of correctly handling both fixed and contained background images for elements that have other overlaying elements over them and displays distorted background images.
