Since segments in OpenGL can be selected, the semantics are a bit different.  Select a segment and a ‘G’ near its end gives you get drag-intersection behaviour while a ‘G’ in its middle gives you drag-segment.

‘M’ works in both cases as well: ‘M’ near an end gives you move-endpoint; ‘M’ in the middle gives you move-segment.

I have my copper trace opacities set at about 55%, and get pretty similar transparency to Legacy.  What values are you using?

Cheers,
Jeff.
