When I use a Look Suite preset plugin and check the "use GPU" box (just above the "do subject" check box) in the effect controls panel, then render, the clip disappears in the program monitor. And, when I uncheck the "use GPU" check box, the clip reappears in the program monitor.

The clip renders much faster when I check the "use GPU" box but it disappears as stated above. Any ideas why this happens?
