Jagged plots when using MRO-3.5.1 with Jupyterlab

[raivivek]

For some reason, it appears that when using a MRO-3.5.1 Kernel with Jupyterlab produces PNG plots that have jagged output (likely no anti-aliasing). When I switch to base R-3.3.3 version, everything looks great!

I have cairo functionality and everything else I could find on internet appears to be as expected, so I'm not sure what the problem is. I installed MRO through Anaconda.

I also tested with R-3.5.1 and the plots look good. So it appears to be a problem with MRO build itself (see also: https://github.com/ContinuumIO/anaconda-issues/issues/10280)

I just tried to MRO 3.5.1 and the plots look good to me. Am I missing something?

I figure that there are so many elements involved in this setup that it's too time consuming to tell where the problem actually is. Most likely it's some Anaconda related mess. Thanks for responding nonetheless.
