Version: (using KDE 4.3.0) Installed from: Ubuntu Packages Opening the Video tab in the Kopete options locks up the UI. Confirmed in KDE 4.3 in Kubuntu 9.04 and Fedora 11, so I think it is a KDE problem. Thanks.
Yes I can confirm that on Fedora 11, whole desktop becomes slow when webcam starts.
Two questions: 1. What model of camera are you using? 2. What kernel module for the camera is being used?
