No, this bug is just a graphical glitch. The symptoms of this bug are being able to see, but not interact with, Unity's panel or launcher on top of fullscreened (Alt+Enter/F11) windows. It doesn't affect keyboard interaction.

In some cases it may affect mouse interaction, if the panel or launcher are responsive at all (they usually are not, because input is layered correctly in X11).
