@johanvos Hi Johan, Great to see all these unit tests getting green so fast! Unfortunately, the provided Test Application still behaves very buggy - I would even say it still is equally buggy, which is quite a suprise. Nevertheless, this is a great step forward. So there must be something the tests are missing. I haven't found out yet what. Maybe they will behave different, if they are executed as a system test, with a real window? I will keep you posted, when we've updated the tests. ------------- PR: https://git.openjdk.java.net/jfx/pull/712
