Nice find!

The issue is not CJK specific. It reproduces when having word wrapping on and rendering line numbers and opening a file with more than 999 lines, and is more obvious when opening a file with more than 9999 lines. The line numbers need to occupy 4 digits or 5 digits, and this information is not taken into account until the first relayout. e.g. a resize.
