openni_viewer very slow

I'm writing a clone of the openni_viewer example app, and it seems to be running extremely slowly and dropping frames. Has anyone else encountered this with the original version?

As best I can tell, it has something to do with the pcl::visualization::ImageViewer class, since calling image_viewer_->spinOnce (); is taking up to 60ms.
