I love the process on this for now... I've been testing it all the time on my Virtual Machine and I was impressed. Now I finally installed Windows 8 on my PC and yes: it's truely nice to see the Windows 7 like borders back. My PC has two monitors. Sadly the effect only applies on the main monitor: the effect is visible at http://l0nk.org/transition.png My main screen has a resolution of 1920x1080 while my supplementary screen is 1360x768 - you can clearly see the gap between the two monitors where the window rendering instantly stops. Other than that.. it's been stable for me, very very great work!
