Thanks for the reply.

The qt terminal for Cygwin works fine on Cygwin, if a patch is attached to
QT5.
An exapmle snapshot of qt terminal is shown :
<http://cygwin.1069669.n5.nabble.com/file/t3087/transparent_solids_2_qt.png>
I will ask Yaakov Selkowitz (qt for cygwin maintainer to apply the patch)
As a reference, the patch is shown below

Yes. It's a bug wxWidget. I could not find wxWidget maintainer in Cygwin
ML.
How I do know the maintainer?
Anyway I will paste wxt terminal and x11 terminal snapshots.

Do you mean build Cygwin's WxWidget without x11 libraries?
On macOS, WxWidget is built without X and uses macOS original graphics.
In principle one can build Wxwidget for Cygwin using windows native api
like emacs-win32on Cygwin.
I do not know that this is possible on wxwidget on Cygwin.
I will investigate.
