the amarok tray icon tooltip appears pretty much in the top left of the corner instead of over the icon? is this just me?
kde 3.5
1.4.5

Since I'm with Debian lenny (KDE 3.5.7) I have the same problem, but with Kubuntu feisty fawn I never got something like that. Someone can help us?

I'm running Amarok 1.4.6

I've experienced this a number of times, through a number of amarok versions even back as far as the 1.3 days and a number of kde versions from 3.2 to present. The only way I've managed to fix it is to trash my ~/.kde settings. Back up what you want from there before you delete the dir. I've never bothered tracking down exactly which setting causes the problem, but it doesn't seem to be amarok specifically.

If someone wanted to do it systematically, I'm sure others would be grateful

It doesn't work in my case: now the tooltip not appear. 

take a look at this topic

In my case work well
