I was just about to file this one myself, after verifying that the previous
package didn't have the problem.  I see this myself in mutt and mc.

Personally, I think it may have something to do with changes made in
xterm-221:

Patch #221 - 2006/10/1
 * fix for regular expressions: the code which converted the column offset
   within a line did not check properly for the end of a line, and if
   allowed to match the whole line, would select the beginning of the
   following line. If the following line were empty, in turn it would
   select from the next, etc. (report by Sean Reifschneider).
 * minor optimization of color allocation to avoid repainting the screen if
   the corresponding color had not been allocated.
 * fixes for vttests/256colors.pl (report by Egmont Koblinger).
 * add terminfo building block entries for modifiers of the 6-key editing keypad.
 * fix for initialization of tek4014 which broke on QNX 6.1

"avoid repainting the screen" sounds very like what I'm seeing in mutt.
Layout inside the xterm window is correct, it's just that characters are...
missing.
