Comment (by mthorn66):

 I believe I am the user that Thomas Dickey referred to.  Until now I
 hadn't established a Github account so that I could comment on these
 tickets directly.

 I have seen similar drawing issues with a recent MacPorts xterm when I use
 the faceName resource to specify the use of a TrueType font.  In my case
 my typing is not shown until I make the window lose focus and then regain
 focus again. I verified that my problem went away if I rebuilt the xterm
 port without configuring --enable-double-buffer, so, yes, I think this
 problem was caused by the change to add --enable-double-buffer.

 As Thomas Dickey writes, yesterday I found a possible fix in the xterm
 source code for this issue and forwarded it to him.  In the process of
 doing this, I also found that telling xterm to use an underline cursor
 (-uc) causes xterm to update the display when the cursor is drawn and
 mitigates much of the problem.
