Description Bill Nottingham 2008-10-23 15:17:01 EDT
Description of problem:

If I change the cube to use /usr/share/system-logo-white.png (i.e., the same logo that plymouth uses), it doesn't render correctly. Various colors bleed over the cube.

Version-Release number of selected component (if applicable):


How reproducible:

Every time.

Steps to Reproduce:
1. Change what graphic to put on the cube

Additional info:

Intel 965, if it matters.

This is a feature of gdk-pixbuf-composite:


"When the destination rectangle contains parts not in the source image, the data at the edges of the source image is replicated to infinity."

This is how it knows which colour to paint the areas around the image (by simply extending the edge colours). So if you put an image with a solid green background, the whole surrounding area would be green.

Most sensible way to fix this would be to add an extra line of background pixels to system-logo-white.png.

Ray, Máirín - was this fixed in the new & improved system-logo-white?

looks to be fixed from getting the eye dropper out with gimp.
