Description Thorsten Wagner 2021-03-16 12:08:27 UTC
On macOS text is displayed retina sharp due to tdf#138122. Images are still rendered using single precision.

Steps to Reproduce:
1. Open LO and look at Startcenter's main display without document thumbnails
2. Open e.g. a Writer document with bitmap images emdedded

Actual Results:
Images are displayed with single precision causing slight blur due to apples upscaling algorithm

Expected Results:
Images that are available in double precision (retina quality) during rendering are displayed in retina quality.

Reproducible: Always

User Profile Reset: No

Additional Info:
Implementation earliest after tdf#141063 has been fixed

FWIW: the icon quality is really really bad on macOS, however the icon not that crisp on Windows either with a 'regular' low res 23inch 1080x1920. especially  noticeable with extra large icons.

So suspect multiple problems..
