> Is it always the same icon? When you re-launch the applet, do you have always the same problem (always the same icons with the same sizes and the same order)?
It can happen with any icon in the notification area, e.g., with the mail notification icon from evolution. If the dock starts and there is new email, in some cases the icon is drawn correctly, in other directly with start-up of the dock, the icon is drawn larger. I can provoke it by starting an application which places an icon in the notification area, until all icons are drawn too large. If you like, I can make an animated screen capture and attach it to illustrate the process if this helps to understand this issue.
