It seems as if the Leap (Devices VL) Node stops sending data after some time. Sometimes after a few minutes, sometimes after hours. This could be a VL/VVVV bug, because whenever this happens, the hands are still tracked in the “Diagnostic Visualizer” in the Leap Control Center. “Allow sending data to apps in background” is on, so it should still work in VVVV even if it’s not in focus. (The only thing which brings the data back to VVVV again is manually refreshing the Leap node with ALT+ right click). Any solution on this?
I experienced this issue with beta36_x64 on win8.1 and win10.
