the netload plugin works for me because I increased the update timeout
to 1sec from the default which is much less.

The real reason for the disappearing tooltips is that in GTK 2.16 a bug
in the previously changed tooltips code was fixed so that the new GTK
tooltips timeout setting is respected which is set to 500ms by default.

The systemload and netload plugins update their tooltips every 250ms
(systemload) or at a configurable interval (netload). And if these
intervals less than 500ms, the tooltips never show.
