First, I apologize for posting here and to Github and then dropping out of sight. I'm doing this from work, and took some vacation last week, so I submitted the issue and promptly disappeared for a few days.
Issue 1428 is my issue, and is the primary reason I asked about this. I'm attaching a screenshot of the new dialog appearance as of 1.30. I do think this may be OS X specific, after updating my Windows machine and not seeing anything similar. I don't currently have a linux machine running a GUI available (my Gentoo box is headless and I haven't installed any X libraries, so X forwarding is out), so I can't speak to that.
