Screenshot: sizes 5 pt, 6 pt, 7 pt, 8 pt and 9 pt
I wrote a text in LibreOffice writer in the size 7 pt (Scale 100 %) and saw that dot, comma, colon and semicolon are drawn poorly in this size. Sizes 5, 6, 8 and 9 however are ok.
In the screenshot you will see the sizes 5 pt, 6 pt, 7 pt, 8 pt and 9 pt in the bold font-face.
The normal and the italic font-face are ok, however.
I use version 2.33.
Version 2.34 on Linux64. Now size 7 is okay, but size 6 is has faulty dot, comma, colon and semicolons. Sizes 4 and 5 are also good. See second attachment.
