Updating TexLive solved the issue. Thanks everyone.

Thanks for this. I'm using Debian Stretch's own distribution of TexLive which
is basically a snapshot from 2017-01-23.
The problem occurs with the follow pdf outputs in LyX: LuaTex, ps2pdf,
pdflatex.Everything works as expected with XeTex in LyX.
I suspect the problem is NOT in LyX because, exporting Tex formats from LyX and
then compiling directly, produces to the same results.
I might have to move over to a direct TexLive installation. I wish we would
have a proper flatpak (https://flatpak.org) bundle of LyX+TexLive-full for all
I'll report back if I have some success here.

Same beahviour with updated TeXLive, the color of the X box is OK.
What could we check next? the exported .tex file? Attached.
