VS2010's WPF renders poorly inside a Windows7 VM?

Solution

WPF renders stuff on a Direct3D surface. It's able to take advantage of hardware acceleration features provided by graphics cards to improve performance. Under VMs, these features might be unavailable.

Problem

Kevin Hoffman this morning reports that: When put under a virtual machine running Windows 7, VS2010 fails to render things, borders disappear, windows become unusable and the experience is downright awful. On the other hand, when you run VS2010 "bare metal" with no virtualization between it and your video card, everything is beautiful and all works well. What about a virtual machine would cause VS2010's WPF to render poorly?
