Probably the same problem as #73120.

I don’t see any blurriness in that screenshot. I’m looking at the red “Are you SURE” prompt, and all of the text is exactly aligned with the pixel boundaries. The strokes are all exactly one pixel wide, etc.

@db48x If you look closely there are light red pixels around the vertical strokes of the characters.
