Sauerbraten - Startup/loading screen renders text and widgets as blue silhouettes

Binary package hint: sauerbraten

The startup screen renders the loading progress bar and all text as blue silhouettes - consequently none of the text is readable. This happens regardless of the rendering mode used; it affects fixed function (-f0) as well as per-pixel (-f3). Note the "Initializing..." text looks fine (so texture fetch and alpha test is probably okay) but some other render state seems to be fubar-ing the color output (fog? color mask?). I'm running on a Dell Inspiron 9400 with a Radeon Mobility X1400.

I've attached a screenshot showing the problem. On one occasion trying to grab a screenshot of this caused the machine to lock up *HARD* (creeping LCD whiteout, widespread screen corruption, fireworks and everything but a kernel panic).
