I have a script that creates and then deletes previews for internal purposes. If the rendering of the preview name extends outside the borders of its preview rectangle, then sometimes the preview name is not completely erased from the main view when the script deletes the preview. Usually as soon as I activate another window, the offending window is redrawn and the problem disappears. See attached images. The first image shows the previews created by the script with extra long names to make the problem more apparent. The second image shows the problem after the script deletes the previews and creates a new window. You will see a partially erased preview name at the top. Sometimes more than one preview name remains unerased.
