See the attached files for the difference; both are from the same host - one from new, and the other from existing session. The only way out I've found is to quit and launch vim again. Does any one know why this happens and/or how to fix it?

Please show the text output.

Another thing that is likely to be the cause is, Vim is using the
VisualNOS highlighting group. This is used, when Vim cannot connect to
the X Server. You mentioned using tmux and re-attaching sessions, so my
guess is, the re-attachment made Vim not correctly reset the X connect.

So the different highlighting is a way to let you know of it.

There was an issue about Vim not correctly resetting up the X
connection, (I believe #3649) and a fix seems to have been included by
8.1.0615.

Best,
