I tested this on my main system which has 3 monitors AND on my other system which has one monitor.
The system with one monitor performed perfectly.
The system with 3 monitors has issues so severe that it makes using this application nigh on impossible.
Both systems had Windows 10 installed in 10/2019, both are fully up to date including drivers.
I have heard various complaints about the performance of TB from community members over the past few years, as I was never affected by them I could not reproduce them, but I am now so I'm making this report.
TB Log from System with 3 monitors: {F1578690}
TB Log from System with one monitor: {F1578683}
