Is it just me or are the various gradients in the new default wallpaper not smooth. Too much compression? I have to admit that I have only seen it hosted on various blogs as I am not able to install from a CD yet. For example this one:http://www.ubuntugeek.com/wp-content/uploads/2010/03/warty-final-ubuntu.png. Have a look at the left hand side!

That's a lens flare effect.

That's a lens flare effect.
Indeed.

Not that, I can see that.
Further to the left of that.
Light to dark.
Probably got the terminology wrong!

I don't like it that much either. They should have used the flame effect.

I see what you're saying, and I'm still pretty sure it's from the lens flare. It's not a perfectly smooth gradient, it has some grain to it.

I am using 9.10, and for my background I used the flame effect in gimp.

It may just be your monitor, on mine I can see some slight banding in the gradient but on my monitor at work the gradient appears fairly smooth.

Your not crazy sams9 !
There is definitely some banding on the left part of the image. There are five or six distinct "halos" in between the color changes... These have nothing to do with the lens flare effect in the image.

Here, you can see it better in greyscale cropped to 200%

It's annoying! Once you see it you can't un-see-it... just like the arrow in the fedex logo :)

The whitespace between the E and x forms an arrow...I didn't see it for years!

cubeist,
That's it, that illustrates it nicely.
Do you think that is due to compression?
Anyway hope they change it.

Yes, probably compression, but I have also seen this when an image has been drawn as an SVG and then exported to other formats.

If you want to fix it for yourself, open the image in gimp, select a large soft brush, lower the opacity, and lightly smudge the "halos" away.

The default wallpaper on Lucid looks bad on my screen.

The resolution on my screen is 1920x1200 and the wallpaper is 1680x1050; is it possible to find a larger version of it?
