### rviz not clearing point or depth clouds with decay time of 0

My issue

I'm having trouble displaying point and depth clouds within rviz. Specifically, no matter what value I set for the decay time, the point clouds continue to aggregate endlessly. After only a few seconds, this causes rviz to become completely unresponsive.

My setup

• I'm using an ASUS Xtion Pro Live
• I'm using rviz for ROS Indigo, obtained from the package servers (not compiled from source)
• Likewise, I am using the packaged versions of all openni-related packages
• I have an NVIDIA NVS 5200M (Dell Latitude E6530)

Other Notes

• I also managed to replicate the behavior using a compiled-from-source version under OS X
• I am subscribing to /camera/depth_registered/points (a PointCloud2 message), but the same issue occurs with the /camera/depth_registered/image_raw topic when I display a DepthCloud.

Apologies in advance if I'm missing something obvious.
