--- Comment #13 from Matteo Bruni matteo.mystral@gmail.com 2013-02-17 13:13:10 CST --- Maybe my patch is wrong (extra sets of eyes are appreciated), but I find it suspect that every texture format, including those not supporting FBO attachment, are claimed to support blending. ARB_internalformat_query2 spec text pretty much implies that FRAMEBUFFER_BLEND should be a stricter requirement than FRAMEBUFFER_RENDERABLE.
So (guess what) I'm blaming the drivers. I'd be happy to be proved wrong.
