Comment 9 for bug 48289

Okay, I've this issue too.

When I run WinXP, everything is okay and there's no black border.

Here's a snapshot with a digicam and notice how the trash icon is being cut off?

Also please take note that various Ubuntu users have complained about this issue in the forums for quite some time. However, it's strange how so few ever report their issues.
