--- Comment #5 from Ilia Mirkin <imirkin at alum.mit.edu> ---
After some investigation, this appears to be a game bug. It creates a texture
with BGRA4 format, attaches it to a fb, and then tries to render to it. This is
not always going to work in GL - you first have to check if a fb is complete. A
FB might be incomplete for just about any reason, but format support is a big
one.

G80+ hardware supports BGRA4 for texturing but not for rendering. If this
support is disabled, the state tracker will instead create a BGRA8 texture to
back the BGRA4 GL texture, and rendering to that will obviously be supported.

However the issue is in the application.
