I just ran into a possibly similar problem:

   https://cygwin.com/ml/cygwin/2019-07/msg00230.html,

although in my case I could only reproduce it under X11.  Are you running under 
X11 when you see your problem?  And can you boil it down to a simple test case 
or, barring that, send your script and reproduction instructions?
