Fonts pixelated v.6.3.0.4

Hi, after we updated to LO 6.3.0.4 (OS: Mac OS X 10.14.4)
fonts on the document page are shown quite pixelated.

Tried several ways, but no idea how to fix it. Can you help us? thanks.

Notes:
Preferences > Libre Office > View > Graphics Output > Use anti-aliasing (selected)
Preferences > Libre Office > View > User interface > Screen font antialiasing (selected) = 1px

In Libre Office Writer we see all text pixelated, no matter if text is selected or not,
but in Libre Office Calc, text gets sharpen when selected!

Upgraded Os to version: 10.14.6 (18G87) but problem persist.
Is quite difficult to work with so blurry text, so we will try to downgrade LibreOffice to the previous version and see what happen… we hope someone can come with an answer

Downgraded to Libre Office 6.2.6.2 and no more blurry fonts.
