I just received the update to libreoffice 6.1.1.2 on my KDE Neon user edition (fully upgraded). I notice that there is work done to make the suite suit better within kde. Only now Liberoffice doesen't follow the preferred system colors at all. Libreoffice keeps the same colors all the time.
This is an older report (already for 5.4), but is it essentially the same problem you see: bug 113019 ?
You are right! I missed that bug. I believe it is about the same issue. I'm sorry...
No worries, now we can set it to NEW :) Hopefully the upcoming KDE5 integration behaves better. *** This bug has been marked as a duplicate of bug 113019 ***
