I cannot reproduce the problem on Ubuntu 16.04 LTS with the TDF LibreOffice build 6.0.6.2.
Could you check the OpenGL usage, showed in Help->About LibreOffice, please?
For example, in my machine, without OpenGL, the dialog window print "UI Render: default"?
If your LibreOffice uses OpenGL (UI Render: GL), could you try to switch off in Tools->Options->View->Use OpenGL for all rendering, and check the LibreLogo program again?
