TF exception in openni_launch [closed]

edit

Hello all!

I have a problem. When I enable pointcloud/pointcloud2 in rviz, it very hard broke/slow down. And sometimes i have this message:

[ WARN] [1391787768.421410849]: TF exception:
Lookup would require extrapolation into the future.  Requested time 1391787768.378529907 but the latest data is at time 1391787768.368281529, when looking up transform from frame [camera_depth_optical_frame] to frame [camera_rgb_optical_frame]

I use Kinect, Ubuntu 12.04, Hydro. Try used openni_launch, freenect_launch, it didn't help. Before when i used Groovy this problem was not, all worked perfect.

What is wrong? How i can fix it?
