I'm on Kubuntu Maverick x64 with KDE 4.5.4 and fglrx (for ATI).
I notice that since yesterday's kubuntu-ppa upgrade, the smooth sliding of the plasma tooltips when switching focus from one plasma component (for example, pager) to another (like a task manager entry) is no longer available.

Was it removed, or is there a setting to toggle it, or is fglrx a culprit? Any pointers?
