Same thing happens with linux mint 17.2, didn't happen in 17.1 however. The line across the screen is only there when running plank or docky. Line goes through all open windows as well, definitely a bug. This occured immediatly after upgrading from Mint 17.1 to Mint 17.2 both with XFCE desktop.

Status changed to 'Confirmed' because the bug affects multiple users.
