Comment 10 for bug 758782

More guesswork...

This may not be a bug in unity-2d at all. I noticed that when running the 'matrix' screensaver on the ppc, the characters appear purple, rather than green like on my PC. I suspect that there is something more fundamental with the way colours are mapped for accelerated displays (??) The regular desktop colours look fine, the screensaver is running in OGL (software, hardware doesn't work ppc/nvidia)
