When using Logic Pro 10.6.1 the mouse goes extremely sluggish, sometimes more sometimes less. Some time it's going back to normal again and then again to unworkable.
I work on a MacPro 2019 OS10.15.7. I had an older BTT version before 3.3.... and upgrading to 3.553 didn't help it at all.
Maybe it's Logic.... I don't know.
