--- Comment #103 from trainma...@gmail.com ---
The reason for the regression has been identified as changing from using XCode9
to XCode10 to build LibreOffice. Those versions built with 9 look fine, those
with 10 are blurry. As for what changed in XC10, that is well beyond my level,
and most of my searching gets results related to font display "within" the
XCode IDE, not for fonts displayed by apps "built with" Xcode's Command Line
Tools.
I did note back in comment 16 that in Calc, text rendering is great while new
text is being entered into a cell, but once the text is (I guess) handed over
to another portion for display once stored in the sheet, it then appears fuzzy.
The problem seems, from what I have found out, to stem from Xcode10 no longer
using/accepting sub-pixel antialiasing. Some reports have suggested changing
from sub-pixel to greyscale font smoothing as a fix. Again, I don't really know
where to even look, much less what to look for.
So, where to from here? Again, well beyond my knowledge. I've poked around in
the source, particularly core/vcl/osx, but I don't really know what to look
for, so it's largely unproductive on my part. Other apps have adapted, many of
which are also open source, so whether devs from those apps are able/willing to
assist I don't know, but I guess it would start by someone asking them.
And because Apple are implementing code signing etc, continuing to use Xcode9
appears not to be an option.
