Libreoffice sidebar and text selection visualisation problem

I recently moved from MS office to LO and from Windows to Linux. Currently I am running libreoffice 5.3.3.2 on elementary os loki 0.4.1 and I am experiencing 2 problems:

  1. text selection is completely transparent when selecting more than one line of text
  2. the side bar is unreadable

In the last month I have tried several distros and only wit h some of them I have experienced these problems: ubuntu gnome 16.04 (but not with ubuntu gnome 17.04) and elementary os 0.4.1; everything was fine with solus os and fedora (soory I have only one point and I need three to upload an image)
Do you have any idea on how can I rectify this?
