just purchased autocad lt 2021 a couple days ago, running the mac version on a brand-new 16” macbook pro, 2.6ghz 6-core i7, 16gm ram, amd radeon pro 5300m graphics card (also intel uhd graphics 630 with 1536 mb).

question: when i edit an object in any way, i get ‘ghost’ lines showing the previous object, until i pan / zoom / redraw. looking around the forums, i’m pointed to a possible graphics hardware issue...i don't see any mac options at the 'certified graphics hardware' page (https://knowledge.autodesk.com/certified-graphics-hardware?siteID=123112&id=18844534&_ga=2.150403829...), for this or (as far as i can tell) any other mac version.

i'm guessing it's not a setting, but maybe it is.  anyone else bumping into this?
