It's just a minor issue, and I can't say for sure when I first noticed it - after upgrading to F13 certainly - but from time to time my clock in Gnome will throw a wobbly. Not even consistent wobblies, sometimes the weather is missing completely, as now, sometimes only a slice of the weather icon appears, and the time/date display can be garbled. It seems to happen after a change such as booting up or a weather update, I've tried removing the applet from the panel and re-installing it, and even removing and re-installing the top panel. I'm reluctant to try removing and reinstalling Gnome-applets as that can remove a whole slew of dependencies and possibly bork an otherwise reliable install, after all I can live with it, but has anyone else had a similar issue?
