Just tried to repro and I didn't get that effect. Maybe a video driver?

I know my 12 year old can't play some games because they use OpenGL and there aren't any proper Intel drivers for OpenGL on Windows 8. So maybe we're back to the days of Vista, where video card vendors are scrambling to get drivers. But then he was smart enough to hack some settings to make the OpenGL games like Minecraft work enough to it's playable, albeit not full screen.
