Hi Bernhart,
As you see, I moved the discussion to lyx-devel, please try to keep it
here and I'll try to keep you in Cc:.

One year ago I reported here a problem with the display of $int...$ and
$oint...$ and all the other integrals, see the attached pic.
After a longer discussion here I found, that the cause of this problem
was the interaction of LyX with QT5-Qt-5.9.4. Then I compiled LyX with
QT4 and this workaround was fine for me.
Now with LyX 2.3.5.2 there is the same problem with QT5-5.12.7 and again
Unfortunately, it is not my failing memory that prevented from fixing
the bug. Since I cannot reproduce it, it is difficult for me to do
something about it.
Let's start by a shot in the dark: does it make a difference to set the
environment variable QT_HARFBUZZ to "old" ?
Even if it does, I suspect it will not be enough for a long-term fix.
Did I understand correctly that you can compile LyX? Does it mean that
you can try a patch too? A possibility is that Qt does not like (ass
Pavel noted) to have a font with a character at position 1 (which is
where \int lives in esint10 font). We would have to duplicate the
character somewhere else in the font.
