Text in an ofFBo is transparent

Does anyone know why my text in an fbo is transparent. If I clear it to black and draw the string it seems that everything but the text goes black, but transparent where the string is…

I had issues with the ofxGui text not rendering if I had enabled transparency. Are you doing that at any time while drawing text to the FBO?

if you are using it, try disabling it right before drawing the text and then re-enabling it.
