I've been troubleshooting the lag and blinking issues for a week now, just finding this thread today. Good timing - I tried Wim's pre-release drivers and things are better. The blinking when docking Xbox Music on the side in Windows 8 no longer happens, and the general mouse lag does feel better. I wouldn't say it's as smooth as working directly on the laptop (Dell XPS 12), but it's within the realm of acceptable now.

I look forward to further improvements!

Update a few hours later: looks like I spoke too soon. Although the lag is maybe a little better, it's still noticeable. The blinking to black is there, too, but it's different now. It seems to blink more quickly and less often than before. Also, I'm running two DVI monitors and one of them only has the Zune client in "tiny" mode to play some music. When I hit the Windows key to bring up the new start menu, there's a definite pause for a second.
