The workaround here is in the editing. For me, the gray areas are
comments, so many might be just deleted if not needed. If they are
needed, "rubber-band" around the area after Ungrouping down to the
sentence level, and Group it, then under the Group tab, reduce Opacity
as needed to the desired level.
If you need some other color, you have to Ungroup all the way down to
individual glyphs, after which you can rubber-band around them and
adjust color in the Color tab (don't Group them because you can't change
colors in grouped objects).

I've used some LaTeX, but not exactly an expert. It looks like you are
invoking minted incorrectly, and you don't have the pygmentize package
installed, or perhaps not using minted correctly causes pdflatex to
think you don't have pygmentize.
