[IGSTK-Users] Error in Release mode, not in Debug mode

[Patrick Cheng]

Hi Tamas,

Looks like the event: transformEvent is being observed by 
igstkSceneGraphVisualization utilities.

Can you try to turn off the option in your cmake and give it another try?
IGSTK_USE_SceneGraphVisualization

Seems like we are narrowing down the problem now.

Thank you,

Patrick
