Comment 383 for bug 439448

I use update manager once a week and did so this week prior to the networking changes. I did notice very minor panel applet corruption after the reboot. I fixed that by removing and adding back the applets manually and rebooted and "solved" the problem.

The networking changes resulted in an intermittent display bug occurring reproducibly and permanently.

That is a huge change in bug behaviour, but does not mean that this bug is a network bug. It just provides a clue to facilitate bug resolution.
