JDK9 b123 + Win. 10 + two displays (both HiDPI, but not sure if it does matter)
Please run the test code from JDK-8159968 and drag the app from the 1st display to another. Then it is impossible to select the menu items, as the menu
1. appears at a wrong place and
2. vanishes immediately when releasing the mouse button (so can't select any item).
Please see the screenshot attached. Note also that the "Minimize" button has huge size and is located under the app's icon (it appears in the leftmost corner on the screenshot) - that's NOK as well.
