One quircky thing I see often with TeamViewer is, if the laptop you are remoting into has an integrated graphics card or is just generally not a great laptop, your view as the one remoting in is often sluggish or just constantly frozen, while the end user does not see any issue on their side. However if the laptop I am remoting into has a dedicated graphics card, I just don't see this issue. Is it possible that debugger is working and syncing properly, but your side is just sluggish to catch up?
