In testing gtk-xemacs-21.1.11 I see two small visual problems. With
my xemacs window all the way to the right side of the screen, clicking
on "Help" causes the help menu to be displayed with most of the text
clipped off the right side of the screen.
Also, when entering text that goes to the bottom of the screen, the
screen doesn't scroll automatically enough so that the bottom of the
text I'm entering is clipped.
I'm using kde-beta4 if that matters.
