I have the same problem on PC if I resize the browser window. I tries IE and Chrome. If I resize the window to smaller size the logo image dissappears.
Quote :OK, I think I have it sorted more or less. First, my image was a 1000x200 JPG. I changed this to a 800x160 PNG and used a gradient in Artisteer for the logo background. Import this and set as Original Size In Artisteer (4) Header Tab: Length - Sheet Width Height 200px Layout Tab: Header: Sheet Width Sheet Tab: Width 75%
background-image: url("images/object0.png"), url("images/header.jpg");
background-size: 100% 100% !important;
