I don't know in the case of the first files uploaded, but I know what I did in
my case.

It's not only a background with gradient. In the slide I attached I use two
triangles that overlap. Each one has a gradient with also linear transparency
that goes, in a particular angle, from blue to white.

I think that I might have managed to discover another thing. Just to check, I
have done a new slide consistent in a simple rectangle (only ONE) with normal
gradient, without transparency. When I exported it to PDF format, the slide
shown as expected.

However, when I added to that gradient a linear transparency, and I then got
the PDF, I could see some lines similar to what I got in my previous slide and
the ones that were first submitted. So it would seem that the gradient + linear
transparency might be related to the source of this problem (I'll attach the
examples now).
