You should avoid this.

That's a coincidence.

Random problems are to be expected if your PDF has errors.

That's what led to my diagnosis: the image data is truncated.

You get the errror once, for instance if you jump directly to
page 6, you'll get the error too, but if you return to other pages
the error is not repeated.

"iText seems to be supporting" is not really correct.
You are creating a PDF with images that are not complete.
Different viewers deal with these images differently.
This has nothing to do with iText. It depends on the way
the viewer is implemented.

Thank you for sharing your experience.
It's an interesting problem.
I hope you can solve it by getting the images in another way
so that they don't generate errors.
