Affects: ubuntu-artwork (Ubuntu)
       Severity: Normal
       Priority: (none set)
         Status: Unconfirmed

Description:
The new GNOME progress/startup screen features rounded corners and is
'cookie-cuttered' onto the desktop.

This creates areas of high-contrast around the edges:

While this is only tempoary artwork, if the final artwork uses similar
affects if should be anti-aliased against the default brown background
colour before being masked.
