Comment 2 for bug 563163

This also happens with other views (e.g. "Installed Software"). The flickering is less obvious, but the refresh happens in the same fashion (5 times in a row approximately 5 seconds after the initial refresh).

An obvious symptom is that when the refresh happens, the first item in the list is selected with a delay, so the row expands (to show the "More Info" and "Install"/"Remove" buttons). When there is no flickering, the first item seems to be unselected and selected again 5 times in a row.
