Hi, I'm having issues with the glass lagging when I drag windows between monitors. Not sure if you tested it on a hybrid-GPU setup (like NVIDIA Optimus) but it seems that's causing the issue on my computer here. Tried aero glass for windows 8 on another laptop with only an Intel Graphics card and that computer doesn't appear to have an issue. Please fix as the lag can get rather annoying. Also, this issue with NVIDIA Optimus wasn't present in Windows 7. I updated both the Intel and NVIDIA Graphics drivers to the latest version but it seems the issue is still present as it's an issue with aero glass.
