Civ4 screenshot with fbo for offscreen rendering

Wine uses framebuffer objects to handle offscreen rendering by default, this
isn't working so well:

For example, in Civilization IV it results in character portraits rendering
garbage (see attached screenshot).

For some games and apps, this can be worked around by using "backbuffer"
instead, as documented in http://wiki.winehq.org/UsefulRegistryKeys but it
isn't working everywhere, and I wouldn't be surprised if this option was
removed in the future.

This might be a more general problem with Mesa instead of something specific to
radeon.
