I'm having the exact same problem with clearance set to 0.1mm. The annoying part is that while routing, neither Legacy nor OpenGL canvas detect a clearance problem, but the DRC does.
As a workaround I just set the clearance to 0.099999mm, but it would be nice if this could be fixed. It's really annoying to route five traces right next to each other at the exact clearance only to get two DRC errors for each later.
