Provide a clear and concise description of the issue

Using transparency for the theme items bg-game-item-f and bg-game-item-f results in the background image to be repeated in the transparent part instead of an accurate representation of the background image as it would be expected.

Steps to Reproduce

1. Use a background image with a motive.
2. Use transparent pngs for the items bg-game-item-f and bg-game-item-f.
3. Use small icons for the consoles for better visbility.

After booting up, you should see that the background image is repeated in each of the images.
