Well, it's probably because of a text property likeĀ  "very visible",
this one in particular is for the cursor, but I'm sure it's something
related/similar to that, "very visible" it's often translated to
blinking, underline or bold, that's why I think it's related.

Now, to find what is the exact ansi escape sequence that is sent, it's
not very easy, maybe you can check the ncmpcpp source code and see how
the clock is "rendered", or the hard way with an strace.

VM with which OS? What is your TERM environment variable on both?
