Hi Can you show the code you changed rather than making me guess? :-)
Are you increasing or decreasing the font size when this happens? Ie does the number of rows shrink or grow? I think screen_resize_y should be changed to prevent s->cy going negative. Obviously something later on (after screen_reflow) is fixing it up but we shouldn't be relying on that.
