It's not quite clear if you're saying that previous versions of the 
installer didn't have this problem, or you haven't used them?

(Old installer version are available at https://cygwin.com/setup/)

Anyhow, this is all a bit disappointing as we made some changes in 2.933 
in an attempt to improve the behavior in 'DPI change' situations like this.

But now I look again at those changes again... maybe they're not quite 
right. I've made an adjustment in an attempt at fixing this.

Perhaps you can try [1] and see if it behaves any better?

If you notice any bugs that ideally *shouldn't* be fixed, please point 
those out as well :P.
