Somehow the font in the integrated terminal in VSCode is blurry or vague-looking in some spots.
When I looked for a solution, it seemed that it is not as bad as depicted in a post on Reddit, but nevertheless it occurs, not at the beginning of the prompt, but every now and then here and there, while still readable, but annoyingly noticeable.
I think the OP was thinking that it might be possible that the Julia extension to VSCode ships fonts that are of poor quality. I don’t think that’s actually the case, but you never know.
