White box arround icon in notification tray

[joggie]

Hello!

Since I've installed the new Ubuntu 10.04, I noticed the annoying white box around the TweetDeck icon (see attachment).

I have seen several threads from "back in the day" noticing same kind of problem, and so I am wondering, has anyone a solution?

I did find out that Ubuntu uses svg images for the notification tray, and TweetDeck (Adobe AIR) uses PNG. It seems like Adobe AIR only takes PNG as icons, but then again, I don't know whether png causes the problem here!

Thanks :-)

I've also got this problem with TweetDeck (any Adobe Air app) and a few other random applications like Banshee.

Any ideas?
