The new version is very convincing, it does not have high CPU/Memory usage and runs fine. It still lags when you open 4 or more windows. I had only one problem with the new version, the new experimental feature introduced "Force BoundRectangleRedraw" when enabled most of the time I get a black screen with only my mouse pointer on it and when some times it gets past the black screen and runs the program, the aero portion loses its transparency and becomes white. I'll provide you with the screenshot and debug file later.
