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 Additional Info: LibreOffice Version: 6.4.1.1 Build ID: 40(Build:1) CPU threads: 4; OS: Linux 5.5; UI render: default; VCL: gtk3; Locale: en-US (en_US.UTF-8); UI-Language: en-US Calc: threaded

I can't reproduce it in Version: 7.0.0.0.alpha1+ Build ID: 86bc13248c1d9f63b10aac304bdf0361d1dcc47f CPU threads: 4; OS: Linux 4.19; UI render: default; VCL: gtk3; Locale: en-US (en_US.UTF-8); UI: en-US Calc: threaded or at least I can't see any difference. Could you please try to reproduce it with a master build from http://dev-builds.libreoffice.org/daily/master/ ? You can install it alongside the standard version. I have set the bug's status to 'NEEDINFO'. Please change it back to 'UNCONFIRMED' if the bug is still present in the master build
I can't reproduce with latest 7.0.0.0.alpha1+ build. It looks like this is fixed.
