I have a problem with Plymouth. It works pretty well on low res, but on higher resolution some strange video artefacts appear - see attachments.

I use ATI proprietary drivers, if it has something to do with it.

The resolution is set in /etc/default/grub like this:

GRUB_GFXMODE=1024x768

GRUB_GFXPAYLOAD_LINUX=1024x768x32

edit: reducing colour depth doesn't help /end edit

I don't know whether it has anything to do with the current problem, but Plymouth used not to appear at all until I followed these instructions (http://ubuntuforums.org/showpost.php?p=9175901&postcount=4) (or actually I took them from another thread but I can't find it at the moment and these are the same).

Sorry for the quality of the screenshots. I don't know whether it's possible to take them during booting so I've taken these photos with a mobile and retouched in gimp to remove reflections (more or less), and since I'm no pro photographer nor photoshop/gimp master they look as they look. They should do to demonstrate the problem, though. And the problem is these green and red glows.

Same problem here.
I am using a Dell D600 with the ATI Radeon driver.
