I'm running Wasteland 2 Director's Cut (2.3.0.5) on a Ubuntu 14.04 x64 machine.
The game starts properly but at the very first scene of the game (dialog with general Vargas), the interface is missing pretty much everything I need to get going.
The dialog UI is displayed but no button is shown, I can't do anything, clicking everywhere doesn't do anything, ESC key doesn't show the menu (not sure if it should though).
Typing in anything in the dialog box is of no use either.
Here is what I get:

Can I do anything to make the game work properly?
Thanks!
