I am running in GNU/Screen on GNU/Linux (kernel 3.14).

This bug only happens when scrolling down anything else than the first
toplevel entry, because the first toplevel menu is already
left-justified...  And it does not happen all the time.  In fact,
while it is reproducible, it doesnt reproduce the same way everytime I
try it.  Sometimes I need to go down 10 or 15 elements until one gets}
drawn in the wrong position, and sometimes I just go down two or three
items.  I am not sure, but it *feels* like the issue is easier to
reproduce if I hit down-arrow rapidly in succession.

This *feels* like memory corruption, as if the x coordinate is randomly
set to 0 in some situations.
