Created attachment 580 [details] screenshot illustrating the problem The resolution in the session selection box shows the resolution with which the session was started. This information is not very useful, it's not updated when the session is resized. We should consider updating this if we see any value in displaying the resolution, otherwise we should just remove that column.
This might be even more confusing now that the user can't choose an exact resolution when starting a session (Bug 7793).
