I run the version of the test before your fix, and it leaves one of the frame of the screen.

I tested it using this command line:
../jtreg/bin/jtreg -vmoptions:"-Dsun.java2d.uiScale=10" -verbose:summary -a -nr -jdk:./build/windows-x64/images/jdk/  open/test/jdk/java/awt/dnd/ImageTransferTest/ImageTransferTest.java

Plus this change in the test:
    public static void main(String[] arg) throws Exception {
+       String prop = System.getProperty("sun.java2d.uiScale");
+	System.err.println(prop);

It prints 10 in the log.
