(the "^[" at the beginning is green text, in case that is important)
Does this tell us anything useful? It does seem to overlap with the string
I'm seeing.

Not to my knowledge, though it is possible one of my plugins is doing so.

That looks like the xterm version string (but probably not in xterm).
When this happens, what does this do:
echo v:termresponse

Do you execute a shell command during startup?

This sounds suspiciously similar to

https://stackoverflow.com/questions/29939026/what-is-the-ansi-escape-code-sequence-escc

> Does anybody have any idea how I can investigate this?

I'd start by checking your $TERM settings both in your shell:

  $ echo $TERM

and within vim:

  :echo $TERM

and see if they're the same.  Based on your description, I imagine
they both *should* return "xterm" but possibly some variant such as
"xterm-color256" or some other such suffix.

stray control characters appear on vim startup

[John Passaro]

Sometimes when I open a new vim session, unpredictably, various characters
appear on the first line, they look like they are terminal control
characters but I don't know for sure.

For example:
;2R^[[>0;95;0c

They go away as soon as I type over them or redraw the screen.

This doesn't happen consistently or according to any predictable pattern
(at least not that I can discern). It only started relatively recently, and
I don't recall that I've updated vim or made any changes to my environment
that might have prompted it (I'm using xterm, bash-4.4, vim 8.0).

Does anybody have any idea how I can investigate this?

Thanks in advance!
