Spark roster repainting delay and presence issues

Maybe this is not related. But i notice sometimes, that when i bring up roster window after a while it shows some presences and then “repaints” roster and sets correct presences for all contacts. So Spark roster is not updated with new presences if it’s minimized, maybe not only in that situation. Maybe this is causing so often described problems in forums “contact is online, but Spark shows it offline so i have to restart it”. For me it repaints in a second, for someone maybe it takes longer, or it cant do that for some reason at all. Spark is getting correct presence info but GUI is not updating.

Just a thought…
