Description Gregor 2015-08-06 14:56:30 UTC 
I recently had Linux and LibreOffice installed. Impress is opening the acrobat pdf's and text that is highlighted is covered over by the highlight. The highlight is showing up, but not the text. I am not sure how to respond about the hardware question

Blending test PDF

This highlight is combined with text using multiply blend mode.
But LibreOffice have no support for blending modes.
See attached PDF test file for example.

page 2 extracted from attachment 117716 [details] has its highlighted text obscured by the highlight

Remains an issue, the highlights block the underlaying text. As in page 2 of  attachment 117716 [details] extracted here.

Comment 8 V Stuart Foote 2018-12-16 16:31:51 UTC 
As an aside, the pdfium based PDF insert does not render the text highlighting into its bitmap.  But it does handle blending correctly when inserting the "Blending test PDF" of attachment 125910 [details]

Would have expected similar handling...

Problem still exists in Version: 7.2.5.2.0+ running on Manjaro Linux:

I retrieved a .PDF file containing yellow-highlighted text, and only the highlighting is visible on the screen, and only uniform gray appears on the b/w-printed page.
