unable to click on power menu

[randall]

Binary package hint: xorg

I have had this problem off and on since installing this version of Ubuntu. It happens on multiple computers. all have amd processors, chipsets, and graphics (have had this problem with amd radeon 5770 and 5850 as well).

The power menu in the upper right hand corner gets covered by a repeat of the user name image and becomes unclickable. i have to click on the user menu and carefully mouse over to where the power menu is to access the menu.
