[UbuntuGnome] Virtualbox 5.0.22 Seamless mode shows windows as black boxes

I'm having a little trouble with Virtualbox and seamless mode with a Windows 7 guest VM. Fullscreen mode works fine but whenever I switch to seamless mode, the windows are just black boxes, though they can be moved. The preview window in Virtualbox shows things as expected. If I switch back out of seamless mode, the entire virtual monitor is black and I have to save the VM and start it again before it displays normally. Attached is an example of the black box where a window is.

Environment:
Dell Latitude E6540
Ubuntu Gnome 16.04
Virtualbox 5.0.22 r108108
Windows 7 Professional guest

EDIT: So it seems that turning off 3D acceleration solves the issue but I'd still like to know if I can get it working with 3D turned on.
