1. Create a basic hello world OpenGL app, e.g. one that draws a single triangle to the screen.
2. Use windowed mode with vsync on
3. Try alt+tabbing or activating between different windows and the opengl window by clicking.
4. Notice how laggy and slow it is.
5. Try a different window manager besides unity such as xcfe4
6. Notice that this problem no longer exists.
