If the user will create a peer then change the background color, then show the window the flickering will occur. you need to override the LWWIndowPeer.setBackground and call the platformWindow.setBackground from there. The LWWIndowPeer.setBackground is also called during peer initialization so the code above will not be needed. But it will be good to root cause the problem if it is not related to the performance. ------------- PR: https://git.openjdk.java.net/jdk/pull/5373
