I'm not sure it's related but sometimes I see a message from macOS, that my hostname is already taken and it needs to pick a new hostname for my machine. It happens only sometimes after computer sleep when Vuo Editor is running. But the the problem with OSC described in the bug report is happening after every sleep with Vuo Editor opened (even if it doesn't run any composition).
Also, when the problem occurs it prevents only OSC subsystem of the composition from work (composition is running but cannot receive OSC messages) and console keeps outputting the error, also draining a lot of CPU power.
●●●○ — It prevents me from completing a specific task with Vuo.
Steps causing the bug to occur:
Build a subcomposition like on attached image1.
Save in in user library.
Create new composition like on attached image2.
Run and observe events leaving subcomposition (all events should leave it; events from input port outside the subcomposition and also events generated by trigger port inside it – but events triggered inside subcomp. are blocked)
Other notes:
Also, please, look at the information appearing on problematic trigger port (see image3).
