Yes, JDK-8371781 is my issue. I understand why it was marked as
non-reproducible. And that’s the main problem! <br>
This issue is clearly described both in the title — SOMETIMES — and
in the FREQUENCY: OCCASIONALLY field. <br>
I specifically recorded a video to prove this issue —
<a class="moz-txt-link-freetext" href="https://streamable.com/6n72cn">https://streamable.com/6n72cn</a> (expires in 2 days) — <br>
and I was able to reproduce it only on the second or third attempt.<br>
<br>
However, this issue is one of the most insidious problems in JavaFX
on Linux. I talked to users on Reddit — <br>
many people have heard about it. The reason is that SOMETIMES the
menu simply doesn’t appear: a user clicks, <br>
but the menu window doesn’t show up. Because of this, SOMETIMES the
ComboBox doesn’t work — you click, <br>
click, click, but the dropdown doesn’t appear. Maybe, the the window
is shown, but it is UNDER the current window.<br>
<br>

Regarding the second issue, JDK-8372108, I will add your
additional information as a comment and reopen the bug.<br>
<br>
Regarding the first issue, I see the following, which I presume is
the one you filed?<br>
<br>
JDK-8371781: Popup for ComboBox, Menu, and Tooltip is not shown
sometimes in JavaFX<br>
<br>
I don't know why you didn't receive notification when it was
processed and transferred to the JDK project in JBS. I see that it
was closed as not reproducible. Do you have additional information
that would help reproduce it?<br>

everyone,<br>

On November 10, I opened an issue (using the new redesigned
form), and the system showed me the ID
23c3711c-36b1-4b94-a0d3-25bbdcf1b95f. 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.<br>
<br>
On November 16, I opened another issue (using the old form)
about a memory leak in Tab that is related to GRAPHIC. Today I
received a message that the issue is JDK-8372108. 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:<br>
<br>
contextMenu.getProperties().put(KEY, new
WeakReference<Tab>(tab));<br>
<br>
MenuItem close = new MenuItem(..);<br>
close.setOnAction((e) -> {<br>
var t = getTab(contextMenu); // from properties<br>
});<br>
<br>
The issue I reported is related to <code data-start="1059"
data-end="1068">graphic</code>. So I believe that there are
TWO separate problems with tabs that lead to memory leaks.<br>
<br>
