Description Of Issue
From time to time the macOS interface becomes laggy while using Roon (every 1 or 2 days), the workaround is to close Roon (cmd+q) at that point the macOS interface will become fluent (0 lag) once again. Then bring Roon back to work, the issue will happen again later on. I tried to catch it in video the latest times it happened and finally make it today.
I thought it was related to run Roon in full screen so started to use Roon in window mode but I do remember it happened once or twice while running in window mode.
