It sounds suspiciously like this is a bug in the nouveau driver, since it only occurs when using the nouveau driver and not the nVidia driver, and has not been reported against the intel or AMD drivers.

I've noticed the same, it might be a regression from the 9.2 upload, I'll test against 9.1 again to be certain, then bisect..

Yeah, 9.1.4 works as expected.

Looks like upstream 9.2 fixed this too, with commit 3b852f9d52732066bffd498313b3ccae4b615481 "nv30: find first unused texcoord rather than bailing if first is used". This means the fix will be in 9.2.1.

I just installed today's ubuntu saucy ISO [ saucy-desktop-amd64.iso 07-Oct-2013 07:48], which still had the "color rainbow" on the launcher and panels.

After it was installed I ran all current updates which included mesa. Now everything is fixed.

This also fixed gnome saucy which had some unusual display behaviors as well.
