Version: (using KDE Devel) Installed from: Compiled sources Compiler: gcc (GCC) 4.1.3 20070929 (prerelease) (Ubuntu 4.1.2-16ubuntu2) OS: Linux First of all, the applications have to be in the right place. That is, they have to be somewhere where a tooltip does overlap the application and also somewhere where a tooltip does not. First cause the tooltip that does overlap to appear then cause the tooltip that doesn't overlap to appear. It is important that no other tooltips are triggered in between. What happens when the second tool tip appears is that where the first tooltip was gets cropped. Whatever section of the application that happens to overlap with the tooltip gets cropped and the section shows through. Now, it is also absolutely important that the second tooltip does not overlap what so ever, if it overlaps, the bug is not manifested. It looks like the cropping is needed to make sure the older tooltip disappears, but only applications that overlaps with the second tooltip is notified to be repainted. Since the desktop is just a full screen application, it is always overlapped which is why it always paints properly.
