What do you mean with "first paragraph"? If it is the the title of the book, I can't confirm this bug.

I can't see a diference. I also added the same text in italic without bold. On eyery zoom level I could see a clear difference between italic with bold and italic without bold.

I checked it again. It seems to be fine with OpenGL enabled; please try without it..
Comment 5 Dieter Praas 2018-03-25 20:45:20 UTC

Hi Telesto,
Could you please try to reproduce it with a master build from http://dev-builds.libreoffice.org/daily/master/ ?

I'm able to repro.

It's a ClearType related issue (it only occurs when disabled). (https://www.howtogeek.com/howto/28790/tweak-cleartype-in-windows-7/)

Not sure if this a bug or not.. I'm using a non-default setting & limited to GDI rendering

I disabled cleartype but still can't reproduce it.

I'm seeing Telesto uses Win 8.1 and we use Win 10. Might make all the difference in the world.
Comment 21 Dieter Praas 2019-11-16 11:13:22 UTC
Telesto, can you still reproduce it with LO 6.4.0.0.beta1? If this is the case, do you have any possibility to test it with Windwos 10?
