JavaFX popups are displayed in windows that don't have OS focus and therefore do not have the active input context but the JavaFX scene associated with the popup doesn't know this and still makes calls to manipulate the IME. This seems to be triggering a bug in the OS that leads to bad behavior which persists until the user moves focus away from the main JavaFX stage altogether and then brings it back.

same issue without the fix.  I agree - this is likely unrelated.

I won't be able to try with an earlier jdk in the next couple of hours, sorry.
