Fontwork lines not smooth

Fontwork lines are not smooth again, they are rough. This was fixed some time back and was OK in 5.0.0.4 but now not so much.

It was originally in this bug, https://bugs.documentfoundation.org/show_bug.cgi?id=60282&redirected_from=fdo, and was resolved and was ok until now.

Any one else experiencing this in 5.1.0.3?

Update: Looks like its not being rendered correctly on the screen but the printout is ok.
