In a text view, when the tooltip is already visible and replaced by another tooltip it shortly flickers. That is, the tooltip shell is first moved to the new location, after that the size is changed. See org.eclipse.jface.text.AbstractInformationControlManager.internalShowInformationControl(Rectangle, Object)

The ficker disappears if fInformationControl.setVisible(false) is called early in the method mentioned above. That is, it is hidden while doing the update operations.
