Solar System CSS3 sample works poorly on Lombard: freezes happen when opening tooltips about planets.
To reproduce, load http://neography.com/experiment/circles/solarsystem/ into any WebNode application, and move mouse pointer over planet/Sun names to the right. As I understand (and as 2.2.4 behaves) a tooltip with text should appear for every planet, and the planet itself should become highlighted. This often doesn't happen, and the whole application (and sometimes even OS) freezes. Often, application crashes.
There is no such problem in 2.2.4.
