There is nothing to do with video card or even Ubuntu. I'm using Debian jessie (8.3) and I have got an update for LO from 5.0 to 5.1.1.3 and after that one annoying bug in Impress presentation console (actual slide was not visible - it was completely black in presentation console) disappeared but those visual artifacts came in place. I don't now how, but it's a LO bug.
