The bug would seem very sensitive to fonts and X toolkits. With =C3=93scar on the first line, I delete the accented "O", I can very clearly see the rest of the buffer shift up. With =C3=93scar on the second line, I delete the accented "O", I do not see the shift-up. As you can guess, I can only get the bug to trigger for first-line. And I cannot get it to trigger at all with Hindi. So it's not a taller-character thing. It's a combination of that accent and the fringe spacing up top. I'll close this for incomplete diagnosis.
