Also happen on HP Notebook 14 with a Intel HD 4000 and Nvidia 820M. When coming back from suspend the screen is black. Switching to Vt1 and back gives you the authentication box with garbled background. After authenticating you get the desktop with a garbled wallpaper and some odd drawing artifacts in menus. Logging out and back in fixes it.
