Description Jens 2019-08-19 09:17:24 UTC
With the new release candidate of 6.3, the fonts inside documents (at least writer and calc) are blurry, i.e. do not use the high resolution of the display and instead interpolate over 4x4 pixels (I think).
The fonts used for the UI do not have this issue (i.e. menus, icons, UI tooltips etc).
This makes text inside Libreoffice doucments on MacOS very hard to read.

Steps to Reproduce:
1. Start Libreoffice on MacOS
2. Open or create any document
3. Watch blurry fonts (any font)

Actual Results:
Fonts blurry

Expected Results:
Fonts should be crisp and use the HiDPI (Retina) display.

Reproducible: Always

User Profile Reset: No

OpenGL enabled: Yes

OS: Mac OS X (All)
OS is 64bit: no

OpenGL setting is not relevant (both settings cause blurryness)

As of LibreOffice this bug is back, exactly as described previously.

Which is to say that most of the UI is the correct resolution, but all of the document and some UI elements are "blurred".

This is running on an iMac Retina 5K, 27inch, Late 2015
MacOS Catalina 10.15.3

I'd be more than happy to provide any further details required.
