Renjith @Renjithkannath worked on a similar bug, [JDK-8256639](https://bugs.openjdk.org/browse/JDK-8256639): _Test `javax/swing/JPopupMenu/7160604/bug7160604.java` fails on Ubuntu_, and he reproduced the problem on macOS too, yet you have to make popups lightweight, they're heavyweight on macOS by default. He tracked it down to the same root cause. His suggested fix was very similar to the one that @TejeshR13 proposes here. I wasn't convinced at that time that it was the best fix but I hadn't had time to look into it further. Neither have I looked at this code review thoroughly yet. Unfortunately, JDK-8256639 cannot be opened because it contains confidential information in its description. ------------- PR Comment: https://git.openjdk.org/jdk/pull/17081#issuecomment-1860936199
