tiles - game screen not updating

[thromnambular]

I haven't played crawl in a while so I decided to clone the git repo. Everything compiled fine, and the game runs fine until after I select my race and background. When I try to press movement keys, nothing appears to happen. But when I press a key combination that updates the text area (ex. Ctrl-D), the graphics get updated and I appear where I should be.
Here's some images to help visualize what I mean:

I press 9 to open the door. Nothing happens.

I press CTRL-D to update the text area, graphics get updated and suddenly the door is open

I am using ubuntu 14.04 64-bit. I think it might have something to do with SDL2 but I'm not sure.
