I have recently updated to AutoCAD 2022 and have come across a strange bug graphically, where the pointcloud struggles to render the shading colour when I have it set to "elevation shading". The drawing below was produced on 2020 and I didn't have this problem. Now opened in 2022, I have random squares that are shaded incorrectly or use RGB values of the pointcloud points. Panning around exacerbates the problem. The is a reoccurring problem across multiple jobs so I am ruling out anything wrong with the pointcloud.
I kindly welcome any suggestions as I use this a lot.
