Created attachment 88435 [details] Screenshot that shows the problem I have difficulty to get the line numbers to coincide with the lines. At sertain font sizes (achieved using ctrl-scroll), the line height for the line numbers is 1px smaller than the line height of the text. Workaround: Scroll to a font-size that does not have this problem. You may need to use a font that is larger or smaller than you are used to. I am using KDE for Windows (4.10.2), so it may be a windows only bug.
