This glitch appears periodically, and does not go away until I reboot. (might also go away with account log off, didn't test that.)
I'm not all that certain that this is a Start8 issue, however this is the best place I could think of to begin.
Right-click context menus are as the cell phone picture shows. I can not see the items within the context menu unless I mouse over each item. This includes the right-click on the start button to pull up the start8 config menu, right-click on the desktop.
Advice?
Running Windows 8.1 Pro, all the latest updates from Microsoft as well as the latest video card (Radeon HD 5700) drivers from ATI.
