This part of the patch 8.1.1459 looks incorrect:

*** ../vim-8.1.1458/src/screen.c        2019-06-03 22:04:17.840244968 +0200
--- src/screen.c        2019-06-03 22:11:26.973743554 +0200

                + wp->w_height + wp->w_popup_padding[2] + wp->w_popup_border[2];
        popup_attr = get_wcr_attr(wp);

!       if (enc_utf8)
        {
            border_char[0] = border_char[2] = 0x2550;
            border_char[1] = border_char[3] = 0x2551;

                + wp->w_height + wp->w_popup_padding[2] + wp->w_popup_border[2];
        popup_attr = get_wcr_attr(wp);

!       // We can only use these line drawing characters when 'encoding' is
!       // "utf-8" and 'ambiwidth' is "single".
!       if (enc_utf8 && p_ambw == 's')
        {
            border_char[0] = border_char[2] = 0x2550;
            border_char[1] = border_char[3] = 0x2551;


It's most certainly meant to check the condition
*p_ambw == 's'  rather than p_ambw == 's'.
otherwise it's comparing a pointer with character 's'
which makes no sense.
