We're seeing "halos" around certain Xrefs on some yellow layer.  Checked my FRAME, or IMAGEFRAME, and it's set at 0..tried to flop it over to 3 then back to 0 but the issue remains unchanged.  When I try to freeze the halo, it freezes the layer the Xref was imported under; therefore, my Xref disappers. Not only is it distracting on the screen, but it PLOTS! So it's not just some annoying Defpoints line you can't get rid of, it's yellow circles all over the Xref that will show up on paper..

Wow.. nobody's touching this one, lol.. <sigh>......

have you checked ddpstyle? sound like your point style is set to some kind of circle with high scale

DDPSTYLE isn't a valid command in my CAD. DDPTYPE is, though, and a pop up window shows where I can selec various types of "Point Style", if that's what you're speaking of. And, after much trial & tribulation, I am unable to provide a screenshot to validate this point.. Hmm...
