Yeah, I agree with what you are saying. I suspect that the number of options, sliders and settings adds complexity to the rendering rules. I'm honestly pretty satisfied with UDL, especially considering how far it's come from this time last year, when there was still a slate of major rendering problems. There are a handful of things I wish were done differently, like DL blocking lines rendering from centers instead of edges, but for me it's been pretty dependable. I just wish that problems with lag and revealing that others have encountered could be done away with.
