Public bug reported:

When the process list changes (new items added or removed due to
processes termining and being started), the viewport isn't adjusted and
the list simply scrolls up and down making it impossible to get any
information from tip popup (important for example for command line which
rarely fits into the column width). Currently it is necessary to disable
automatic updates in the settings dialog and reload manually if
necessary.

Updates should (1 of the following)
  * be triggerable directly from the process tree panel (e.g. next to the 
update button), on/off is sufficient, a slider (from 0 to x) for update 
interval would be nicer
  * not influence the change of the viewport of the process list or tree 
(depending on whether dependecies are activated or not), i.e. the viewport 
should jump so that the entry stays at the same position in the list. This 
would allow handling information provided by gnome-system-monitor independent 
from updates (sorting criteria and interval), but would require a list or tree 
GUI element that could handle the case that the item moves to the first or last 
position of the tree from a position in the middle in order to avoid the 
undesired jumping behavior described above for items switching from 1st/last to 
a middle position at differnt update steps
