I proposed and implemented snapping vertical positions to the pixel grid after layout: https://gitlab.gnome.org/GNOME/gtk/-/issues/3787#note_1276560 https://gitlab.gnome.org/GNOME/gtk/-/issues/3787#note_127656... The maintainer responded that "[c]hanges to the rounding behavior of glyph positions really belong into pango, though". I understand, but I don't know whether he's suggesting fractional layout but integer-rounded rendering, or integer-rounded line heights and layout and rendering. And I don't know how to change Pango, and lost interest in digging further.
