In a beamer frame, two boxes (minipages, drop shadow) are place in columns
next to each other. Everything works fine, except in the first frame one of
the boxes including text is always red.
The box is OK here (lyx-2.3.0rc2, Debian Stretch, TeXLive 2017).
I'm updating TeXLive (beamer has changed), I'll test again when it is over (528
files to update).
Same beahviour with updated TeXLive, the color of the X box is OK.
What could we check next? the exported .tex file? Attached.
