This has nothing to do with the snapshot.  It's the latest change to
cygrunsrv which re-introduced the short flash.  It's very simple.
Either a console window flashes for a split-second, or you will never
see a console window, but the console window is then unusable for output
from the service application.  There's no way around this for now.
To not lose the output capability, you'll have to live with the flashing
window.
