Description Thorsten Wagner 2020-01-01 23:39:42 UTC

Description:
Text on retina displays, e.g. within dropdown windows of listboxes, Writer document redering, Calc document rengering, is blurry when building LO with macOS SDKs 10.14 or 10.15.

Steps to Reproduce:
1. Build LO with macOS SDK 10.14 or 10.15
2. Start LO
3. Open a document, e.g. with Writer

Actual Results:
Text is blurry on retina displays.

Expected Results:
Text is sharp on retina displays.


Reproducible: Always


User Profile Reset: No



Additional Info:
SDK 10.13 seems to be the only SDK to build LO with sharp text on retina displays.

Minimum SDK release is currently 10.12. Due to API changes between SDK 10.12 and 10.13 which have been incorporated in LO code already, LO cannot be build with SDK 10.12.

Mimimum SDK release should be increased to 10.13. Furthermore LO should be build with SDK 10.13 only until issue is fixed (maybe an issue of Apple within Carbon code).

Perhaps a dup of tdf#122218 (put in See also)

I think it could be interesting you send a message on dev forum (see http://document-foundation-mail-archive.969070.n3.nabble.com/Dev-f1639786.html) or ping devs on IRC (see https://wiki.documentfoundation.org/Development/GetInvolved)

In last ESC, I also noticed:
"
        + After Update to 6.1.4 on macOS fonts are blurred on retina
display (xcode 10)
           + https://bugs.documentfoundation.org/show_bug.cgi?id=122218
             + probably depends on xcode version (Xisco)
             + but newer xcode is required by notorization (Cloph)
               + ideal would be to build with xcode 10 entirely
               + HiDPI screen for Cloph would be great (Michael)
               + found out: not a regression, but it is from a user’s PoV

I think it's a 146% dupe of that bug
