report source and generated pdfs

Take two elements: Grid and Label. Place them close to each other with a little margin to avoid touching. Set 1px border for both elements. Generate two pdf reports with following settings:
1. Default DPI
PDFRenderOption options = new PDFRenderOption();
options.setOutputFormat(PDFRenderOption.OUTPUT_FORMAT_PDF);

2. 600 dpi
PDFRenderOption options = new PDFRenderOption();
options.setOutputFormat(PDFRenderOption.OUTPUT_FORMAT_PDF);
options.setOption(IPDFRenderOption.DPI, 600);

First pdf has a hardly noticeable difference between border line size but it's visible after zooming. Second pdf has a huge difference.

Borders of the same size should look the same after rendering regardless of the element.
