I'm running Libreoffice on two laptops with Kubuntu installed: Lenovo Ideapad 320S and Asus Notebook X207N. Both PCs have the same settings, yet the presentation of Libreoffice is different. Mine is on top and looks great. Wife's looks naff. What's the reason for this?
Solved it by going into Options, Personalisation and chose a theme. For some reason mine looks OK without choosing a theme. Hopefully the Pink theme will score me brownie points with the wife.
The lower image reminds me of instances where LibreOffice isn't "integrated" into the system. In Kubuntu 18.04, with the latest update of LibO to 6.2.2, when I look in Help > About, I see VCL: kde5. Also, when I run apt list --installed | grep -i libreoffice, I see two packages in the output that may help LibO "integrate" (and look) better in Kubuntu: libreoffice-qt5 and libreoffice-kde5.
As mentioned by others, different repositories will install different versions of LibreOffice, and all of them could be different from a brand-new version being offered on the website. A month or two ago, I fresh installed Ubuntu, and the default LibreOffice was significantly different -- also in GUI -- from the version being offered for download on the LibreOffice website.
You will also see differences if you change font anti-aliasing settings (system vs enabled/hinting/color). Mrk
