Icons not showing up in admin area in IE8

Just testing out the beta and I noticed that all icons don’t seem to be showing up in the admin area in IE8: https://www.iliveinabin.com/Img/wp3.8-beta-admin-dashboard.png

Strangely, they do show in the admin bar when not inside the dashboard: https://www.iliveinabin.com/Img/wp3.8-beta-page-preview.png

Apologies if this has been mentioned before, I did search and didn’t see it mentioned.
