About two my issues

[PavelTurk]

Yes, JDK-8371781 is my issue. I understand why it was marked as non-reproducible. And that’s the main problem!
This issue is clearly described both in the title — SOMETIMES — and in the FREQUENCY: OCCASIONALLY field.
I specifically recorded a video to prove this issue — https://streamable.com/6n72cn  (expires in 2 days) —
and I was able to reproduce it only on the second or third attempt.

However, this issue is one of the most insidious problems in JavaFX on Linux. I talked to users on Reddit —
many people have heard about it. The reason is that SOMETIMES the menu simply doesn’t appear: a user clicks,
but the menu window doesn’t show up. Because of this, SOMETIMES the ComboBox doesn’t work — you click,
click, click, but the dropdown doesn’t appear. Maybe, the the window is shown, but it is UNDER the current window.

Best regards, Pavel

The issue was about the fact that PopupWindow is not always shown on Linux systems, and I described how to reproduce the bug using a Tooltip. However, I still haven’t received any information about my issue.

However, my issue was immediately closed with a note saying that it is a duplicate of JDK-8283449. But it is NOT a duplicate. JDK-8283449 is related to a problem in ContextMenu. I know this issue and I use the following workaround:

>> contextMenu.getProperties().put(KEY, new WeakReference<Tab>(tab));

>> MenuItem close = new MenuItem(..);
>> close.setOnAction((e) -> {

>> The issue I reported is related to |graphic|. So I believe that there are TWO separate problems with tabs that lead to memory leaks.
