some new information
1) it happens in a graphics display not a text window (sorry -- I thought it 
happened in both, so I did not specify it)
2) I installed emacs 25.1-rc1 -- the same thing happens i.e.
> pwd
/tmp/emacs-25.1
> emacs -Q  t.tex  #file with 1 letter per line -- a to h
a
b
c
d
e
f
g
h
#I put the cursor at a and press C-k -- it clears to the end of line
#I press C-k again to get rid of the blank line and the display then looks like
b
h
h
h
h
h
h

M-x redraw display fixes it
b
c
d
e
f
g
h

so far I have not found any other key combination that causes a problem

Bye
