MacOS – causing a black screen while switching spaces on Mountain Lion

macmacosmission-controlspaces

On Lion I used to see the next space wallpaper while pressing Control + to switch desktops. But on Mountain Lion I see a Black Screen until the transition is complete. Is it just me who is facing this issue or is this the new behaviour in Mountain Lion?

Its now resolved. It was not an issue with OSX. I was using a software called ScreenShade which was causing this issue. Disabling ScreenShade resolved the issue.
