InDesign versions 15.1.4, 16.4, and 17.0
Mac, system Big Sur 11.6.1

There are no steps or expected results other than stability and quick performance.

No matter what I am doing—working with text or images, scrolling, working in menus, etc.—I am experiencing the rainbow pinwheel and delays of 30 seconds to a few minutes while the application is hung up. This is happening every couple minutes. Work that should take 15 minutes is taking 30 or more.

I've tried disabling the preflight, changed the display performance to typical, allowed greeking, etc., but nothing has helped. I first experienced this in version 16.4 last Friday, upgraded to 17.0 on Tuesday, and also tried using version 15.1.4, but I am experiencing the same problems in all three versions.
