Difference between Grid and Label border size [message #1416131]

Hi,

I'm using BIRT to generate PDF reports. I've noticed a difference between border size of Grid and Label elements. To visualize this problem I've created a grid with 3 rows and 2 labels. Every row and label has a solid bottom border with different size. Can somebody explain me why 1px border of label is much thinner than 1px border of grid row?

What is your BIRT version? In 4.4.0, they are consistent no matter the element.

I'm using:
BIRT 4_4_0-20140611
Eclipse BIRT Designer Version 4.4.0.v201405191524 (should be insignificant because report is in XML)
Eclipse 4.4.0
JDK 1.7
Windows 8.1 x64

I'm creating sample report (in attachment) with options:
PDFRenderOption options = new PDFRenderOption();
options.setOutputFormat(PDFRenderOption.OUTPUT_FORMAT_PDF);
options.setOption(IPDFRenderOption.DPI, 600);
options.setSupportedImageFormats("PNG;GIF;JPG;BMP;SWF;SVG");

Edit:
I had another idea: this could be pdf reader problem, but after opening file with Adobe Reader 11.0.08 and Foxit Reader 6.2.3.0815 problem still exists.

FOUND A CAUSE: setting 600DPI makes disproportion in lines size more visible (see attachments). Both 1px lines in pdf without 600dpi look similar, but they are still different (take a zoom, and count pixels). Still wonder why.

I put the 1px grid and 1px label one over the other. When I do that, I can visibly see the difference at no zoom. Please log a bug for this in the bugzilla and post the info in here for future reference.
