Screen sharing freezes for some presenters
We're experiencing a problem with screen sharing for some of our employees. When they're presenting, the session may start fine, but at some point it will go to a light blue screen with a spinning icon. Looking at the Pop Activity Monitor during these problems, their "Available Send Bit Rate" value drops from 20,000 to only 1,000. If they restart their computer the problem clears up for a while, but it's happening on a daily basis and becoming a significant problem for productivity.
