Thank you very much. Looks better now.

I'm sorry for nudging, but on msys2 I still get frequent mistypes when
typing fast.

I (still) don't have a consistent reproduction, but if I get it
correctly, it looks like one or more characters I type right when the
prompt appears show up before the buffered characters.

For instance, I run git fetch, and while it is running I type git
status, *sometimes* 1-2 characters "pop" to the left, so I get
something like tgit satus.

I wasn't able to reproduce it with cygwin, but on msys2 (with cygwin
3.3 branch merged in) it happens to me all the time :/
