Cloudviewer freezes during visualization

Hi,
I am using sample code:
http://pointclouds.org/documentation/tutorials/cloud_viewer.php#cloud-viewer
to visualize point clouds,but cloud viewer is freezing(0.2fps-1fps) in following cases:
1.Sometimes before point cloud is rendered on screen.
2.Sometimes when i click on other window.

I am using Ubuntu-11.04(64-bit on x86-64 machine),pcl-1.5.

Hi,
I want to add more detail to the problem:
I have vtk-5.4 on core i3 machine.
I have used PCL cloudviewer example(link given in earlier post) on other machine with vtk-5.8 and it was working without any 'freezing' problem.(although that machine is core i5)

So can it be a problem due to outdated vtk library used?
Please tell if more details are required(like code profiler output,process viewer snapshot etc).

Hi,
I linked against vtk-5.8 also,still same problem persists.

Please tell if i need to post additional details.

So you have two machines, both with VTK 5.8, one working and one not? That seems to be an user error -- though it's
impossible to tell, given the information that you provided us with :)

Cheers,
Radu.
