Dash Home menu screen graphics malfunction

[Michael Whittier]

If I open Dash Home menu screen before having opened anything it works fine. Should I open any program or window, then try to open Dash Home menu, I get malfunctions. Usually the icons are visible, but program descriptions are filled in with color, such as a block of red or yellow. Other times the whole menu is blank and turns black upon mouseover. Rarely, it locks up my graphics card and have to restart system by switching to terminal (by using ctr+alt+f1).
