Plymouth displays video artifacts on higher resolutions

[Kamil Kaczmarczyk]

Binary package hint: plymouth

I have a problem with Plymouth. It works pretty well on low res, but on higher resolutions some strange video artifacts appear - see the attachment.

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

Reducing colour depth doesn't help. Plymouth works if these two lines are commented, but then obviously only default low res is in use.

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 instructions from this post: 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 screenshot. I don't know whether it's possible to take one during booting so I've taken this photo 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 this green - or red in solar theme - glow)

The problem is also described in this forum thread: http://ubuntuforums.org/showthread.php?p=9225094#post9225094

One more screenshot, this time from solar theme.

[skillllllz (bmustafa)]

Same exact problem here. ATI Radeon HD 3400 w/ latest proprietary FGLRX driver (2:8.723.1-0ubuntu3) supplied by Lucid's official repo's.

[John Kearns (sundog222)]

Ditto. Except I'm using Kubuntu and ATI Radeon HD 3200. The resolutions and colour depths I've tried are all supported, according to vbeinfo.

[Harry Agámez Pedraza (harry-agamez-live)]

Same problem here with an ATI 4850 and UBUNTU 10.04.
