So on an empty scene, everything works fine. But when I select gameobject with lots of fsms, my editor fps drops significantly. When editor is in that low fps state, I can't properly write to any string field in Playmaker Actions, because for some reason it's often gets deselected when I'm typing. It is really annoying.
Here's a demonstration of the problem.

Playmaker 1.8.4
