It doesn't fix it on its own.. certainly not for the intel driver.

The setTexBuffer hook still explicitly sets the format of the texture to
be BGRA, and I assume it ought to be setting this information based on
the FBconfig (now hopefully correct) of the GLXPixmap the texture is
being mapped from.

Does anyone have any hints how start fixing that?
