ADDITIONAL SYSTEM INFORMATION :
Microsoft Windows [Version 10.0.19044.1566]
java.runtime.version: 17.0.2+8-86
javafx.runtime.version: 17.0.2-ea+3


A DESCRIPTION OF THE PROBLEM :
JavaFX screen is not drawn correctly on Windows (Japanese) high contrast.
I am checking with a combination of a small program and command arguments.

STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
-- batch ---

PATH C:\java\jdk-17.0.2\bin;%PATH%
cd /d C:\java\bell-jfx\a
set arg=-cp bin --module-path "c:\java\javafx-sdk-17.0.2\lib" --add-modules javafx.controls,javafx.fxml
set yob=-Dcom.sun.javafx.highContrastTheme=YellowOnBlack
java %arg% a.T NonE
java %arg% %yob% a.T YOB
java %arg% -Duser.language=en a.T EN
java %arg% -Duser.language=ja a.T JA
java %arg% %yob% -Duser.language=en a.T EN+YOB
java %arg% %yob% -Duser.language=ja a.T JA+YOB


EXPECTED VERSUS ACTUAL BEHAVIOR :
EXPECTED -
Incorrect color, font size, checkbox size
ACTUAL -
I want it to be displayed correctly without specifying system parameters.
