Bug Description
Binary package hint: plymouth
I am using Kubuntu 10.04. When I boot my system, the splash screen shows a lot of glitches - I can barely read "Ubuntu", and the overall picture looks almost as if it tried to reduce the color depth, but it did not use the nearest color when reducing, but some random one (the glitch does not always look the same).
The graphics card is an Radeon Mobility 7500 - yeah, quite old ;-)
As soon as X starts, the splash screen looks all right. The same happens, in reverse order, when shutting down.
