In a document editor, new files begin with text rendered in a familiar font, one with serifs—small lines extending from the ends of letters.
Opening new documents, entering text, and selecting from the font menu proceed consistently. Previews in the menu display the same styles, and saved files reopen with matching appearances.
In a subsequent new file, the text adopts a sans-serif font, composed of straight, unadorned strokes.
Prior documents continue to show serifs upon opening. The font menu lists both options unchanged, yet fresh documents now use the sans-serif by default.
The default font for new documents has shifted, with document handling appearing uninterrupted throughout.
