While using the adjustment brush I am frequently getting the "spinning beach ball". Lightroom becomes very sluggish to the point of being unusable. Also, white boxes are appearing on my image in the develop module (see attached photo). The white boxes are not on the image in the library module but as soon as I go back to the develop module, they are there.

 

Just recently installed MacOS Catalina on my system (clean install). Re-installed Lightroom Classic and Photoshop. Never had this problem on Mojave.

 

Any help with this would be greatly appreciated. Thanks!

 

Machine specifics:

MacOS Catalina 10.15.7

iMac (Retina 5K, 27-inch, Late 2015)

32 GB RAM

2TB internal SSD

Graphics AMD Radeon R9 M390 2 GB

 

Lightroom Classic 10.1.1 

Camera Raw 13.1

Many many MACOS users with various Apple rigs, various MACOS versions, are having huge problems with LrC v10.1.And LrC v10.1.1 only fixed one issue, of no help to most MACOS user problems. Consider rolling back to LrC v10.0 Mant threads on this  in this community.
