My MP 6,1 is lagging badly when I use LR Classic with two 4K monitors. It is especially bad with local edits; e.g., spot removal. I set the 2nd monitor in Loupe mode, and zoom in the photo in the 1st monitor to remove spots. Then the beach ball would appear **twice** for each spot removal before I could do anything next. This is with the latest LR Classic V10.1. It is slightly better with V9.4
If you have a M1 Mac Mini, Lightroom Classic, and use it with two 4K monitors, could you please try the above steps and see if it works well with your M1 Mini?
