            Bug ID: 131214
           Summary: PNG images without alpha channel appear blurry in
                    LibreOffice
           Product: LibreOffice
           Version: 6.4.1.1 rc
          Hardware: x86-64 (AMD64)
                OS: Linux (All)
            Status: UNCONFIRMED
          Severity: normal
          Priority: medium
         Component: LibreOffice
          Assignee: libreoffice-bugs at lists.freedesktop.org
          Reporter: jh_lobugs at outlook.com

Description:
If a PNG image is inserted to a LO document after removing its alpha channel
(e.g. by ImageMagick convert -alpha remove), it will appear blurrier.

This seems to be limited to displaying the document in LO only. In the exported
PDF, the image is clear as expected. When the LO document is directly opened in
Microsoft Office, the image is clear too. I first noticed this in Impress but
Writer seems to be affected too.

Steps to Reproduce:
1. Insert a PNG image without alpha channel into a LibreOffice document.


Actual Results:
It appears blurry.

Expected Results:
It should be clear.


Reproducible: Always


User Profile Reset: Yes
