Description thdeppner 2018-12-20 10:37:04 UTC
After updating to 6.1.4, the fonts displayed in LO Writer are displayed in a blurred way on a MacBool Pro with retina display.

Only the rendering of fonts in the document window seems affected, fonts used in LO menu items are displayed correctly (crisp). 

Downgrade to 6.1.3 resolved the problem.

Did not test with other components than Writer. OpenGL not enabled; switching it on made no difference.

Steps to Reproduce:
1. Start LO Writer.
2. Type a couple of letters.
3. Realize they are displayed in a blurred way.

Actual Results:
Font in Writer is displayed in a blurred way.

Expected Results:
Font in Writer is displayed correctly (crisp).

Reproducible: Always

User Profile Reset: No

Blurred text in Calc
Comment 3 Maciej Tarmas 2018-12-20 11:33:24 UTC
Not only affecting Witer. Also note the blurry interface text in the status bar at the bottom.

Note that when selecting text in a spreadsheet cell, text becomes sharp.

Nope, deleting the profile doesn't do anything about the issue.
Comment 6 Wojtek 2018-12-21 13:18:28 UTC
Came here to report same issue - fonts are blurry in Calc and Writer (those I use). After selecting the cell the font becomes very clear (actually better that normal display in 7.1.3 as well)
Comment 7 Alex Thurgood 2018-12-21 14:35:31 UTC
Don't seem to be able to reproduce this in either Calc or Writer on a Macbook Pro 2015 with Retina display connected to a Thunderbolt (HiDPI) display.

I tested against the default LO font Liberation Sans.
Build ID: 9d0f32d1f0b509096fd65e0d4bec26ddd1938fd3
Threads CPU : 8; OS : Mac OS X 10.14.2; UI Render : par défaut; 
Locale : fr-FR (fr_FR.UTF-8); Calc: group threaded

Is the issue only with Microsoft fonts, or particular font families ?
Comment 9 Maciej Tarmas 2018-12-24 20:36:48 UTC
No, the issue is with all fonts. See the screenshot with Liberation Serif in Writer.

Once again, the font in the status bar at the bottom of the window is also blurred.

OK, it would have helped having some comparison of before/after, so I did it myself...

First screenshot taken with document in Writer using LO5472
Second screenshot taken with same document in Writer using LO6412.

Notice the marked decrease in font display rendering in the second screenshot.

===> regression

Please, redownload LibreOffice from
https://www.libreoffice.org/download/download/ and reinstall it. We had to
rebuild it with xcode 9 to fix hang/crash problems with Mojave

@Xisco : pretty certain this isn't a DUP of bug 121778.

The screenshot I posted used the 6142 release built with XCode 9
