I've been using Ubuntu 12.04 since it came out and so far didn't have any problems with it. But after I updated (via Update Manager) it yesterday, after every reboot, the launcher color defaults to a blue dash, workspace and trash icon and the rest is black. If I set the wallpaper again manually, then it changes color as its supposed to (chameleon).

Any idea why this is? Its really annoying to change your wallpaper every time you logon just to get the "normal" launcher.

EDIT

The chameleon effect works perfectly for notifications. Only the Launcher and Dash are not changing the color.

Thanks.
