vim8.0 bug: syntax highlight breaks for "big" text file

I recently updated my cygwin and I found my vim (8.0 1-1052) does not work well on asciidoc syntax highlight.

* the issue is weird:

1. I start my file: vim temp.adoc, I see file opened with correct syntax highlight
2. C-G to go to the last line, syntax highlight is gone
3. gg to return to first line, syntax highlight is still gone.

* but this works:

1. open file
2. page down, OK
3. repeat 2 till the end of file, OK
4. go to first line, OK
5. go to last line, OK

* also, it looks file size matters
1. if the file is small, like 2 or 3 screen down the end, I don't see the issue.
2. the issue can be replicated with the attached file.

* I tested with markdown file and found the exactly same issue.

* I had another cygwin environment in same laptop, with a diff vim version (7.4 1-752). that one works fine. 
* I compared the asciidoc.vim syntax file between the two environment and confirmed they are the same one. 

I'm thinking this must be a bug in vim8, unless I'm missing anything here...


//to narrow down the issue I tried this:

pings@PINGS-X240:~$ vim -V2 -u NONE test.adoc

:nocp
:syntax enable
