You mean, adjust_frame_glyphs, right?
We probably should do that, but my problem is that I cannot reproduce
the original issue: whatever I try, the condition
it.current_y < it.last_visible_y
happens before
MATRIX_ROW_VPOS (row, it->w->desired_matrix)
>= it->w->desired_matrix->nrows
We need a recipe to trigger the reverse, to be able to test a
solution.
