C:\emacs-27.0.50-snapshot-2019-09-18-x86_64\bin>emacs -Q --eval "(setq w32-pass-lwindow-to-system t)"

Emacs which I uses is downloaded from http://alpha.gnu.org/gnu/emacs/pretest/windows/emacs-27/emacs-27.0.50-snapshot-2019-09-18-x86_64.zip.

I don't know how to compile emacs on windows.

That revision is more than three months old:

Could you please try with a recent snapshot from master?

Also surprising:

I thought Emacs could not be cross-built. Are you crossbuilding from Windows to Windows (assuming that's even possible)? Why?

Do you happen to have a non-standard lisp/loadup.el perhaps?
