I use Windows 8 on a virtual machine through a VNC connection. The VNC server is integrated into VMWare so that even if I lose network connection on Windows 8, I can still access it.
Overall, my experience with it is pretty tolerable, except for when I go to the start menu. Bringing up just the start menu doesn't induce any amount of lag, but when I have to scroll it literally takes 5 to 10 seconds for the screen to draw for the 2 or 3 frames of scrolling. This is very annoying and is the only thing like this. Honestly, I don't really understand why it happens here either as it looks like something perfect for copy-rect to make fast. (ie, scrolling in firefox doesn't have this kind of behavior)
Anyway, has anyone else had this problem and know of anything to try to make it better?
