Using a dual-display setup on a quad-core, win 7 desktop computer, whenever I join a Google Plus hangout, my mouse slows considerably down. Problem persist even after closing all Chrome windows.
Problem is triggered during the start of the plus window. No other performance degradation observed, and my CPU utilization is level around ~7-8%.
Might be relevant: using a Logitech webcam.
Any ideas as to why this might be happening, or hacks to work around this problem?
