Thinkpad X220 HD3000 Issues on Sierra

Hi, I've managed to install Sierra on my X220 with no real issues, however, I can't get the HD3000 graphics to work properly, as it's only showing 4MB of VRAM for the chip. I have the native 1366x768 resolution working with no issues, but there's no transparency effects at all, and the login screen background is just grey.

If anyone could please point me in the right direction on how to fix this, it would be much appreciated. Thanks.
