[Pkg-lyx-devel] Bug#858535: lyx: Does not display ooint symbol

[g.gragnani]

Package: lyx
Version: 2.2.2-1
Severity: important

Dear Maintainer,

at my site the  math symbol \oiint is no longer displayed when using the
math editor. Is is however inserted in the tex source code, but not
seeing it makes the program prone to typing errors.
I checked also the doc file abouth math that comes with LyX (LyX's
detailed Math manual) and also in this case (in subsection 10.1) the
symbol is not displayed on the screen.
