The patch is on the Piglit list if you want to use it ("Test transform feedback with intervening glReadPixels."). Incidentally, I've sent a bunch of new transform feedback tests to the piglit list in the last week. I'm not going to try to pressure anyone into code reviewing them until the new year, so if you want to use them before they get reviewed, feel free to pull from branch "xfb" of git://<a href="http://github.com/stereotype441/piglit.git">github.com/stereotype441/piglit.git</a><br> <br>Happy holidays!<br>
