Hi. Under VirtualBox 4 (host: ArchLinux x64 running kernel 2.6.36-ARCH, NV 9800GT, using official binary driver), both default and alternate shadow rendering is broken:

As far as I know, VirtualBox uses WineD3D for Windows to translate Direct3D calls into OpenGL, and Chromium to offload 3D rendering to host OS.
By the way, everything else seems to work just fine.
