Transparent png image

Transparent png image (attachment) makes font thicker on pdf-export. I removed the image and pdf-export was correct. Document was 110 pages long and written with 'DejaVu serif' font (size 11).

Version: 4.1.2

Specs:
Operating system: Windows 10
Processor: Intel i7 2600k
Graphics Card: Nvidia GTX 770
Monitor: Asus 24" monitor

I was not able to Replicate the bug. Here are the tests I did to try and replicate the issue. I first made a "control" file that the test files would be compared to. After every test file was made, I compared it to the control file.

Making the control file:
1. Download the picture attached to this report
2. Open OpenOffice.
3. Write or copy/paste a paragraph of filler text.
4. Copy and paste the paragraph until the file is 193 pages long.
5. Click File->Export as PDF. Click Export on the new window that pops up.

Test File 1:
1. Make a copy of the control file
2. Open the copied file in Open Office
3. On the top bar, Click Insert->Picture->From File, and select the picture downloaded from this report
4. Insert the picture AFTER all the text
5. Click File->Export as PDF. Click Export on the new window that pops up.

Result: Font was not thicker in test file 1

Test 2:
As Test 1 , but insert the picture BEFORE all of the text

Result: Font was not thicker in test file 2

Test 3:
As Test 1 , but insert the picture in between any two paragraphs or lines of text

Result: Font was not thicker in test file 3
