I get a bunch of errors mentioning Nullrefs, Invalid editor window, Missingref when having certain Playmaker tabs active in the editor upon Play with Maximize On Play toggled on.
These eventually results in flickering black areas which overlap all editor visuals, and only way to fix it is by restoring to a previous Unity editor Layout or reset the layout all together.
This does not seem to be the case for the Playmaker Editor tab itself, as I've never had errors for this one specifically.
I often have the tab "Actions" active in the editor, and quickly forget about it when I hit Play.

If example the tab "Actions" and "Hierarchy" tab share the same window where the Hierarchy is active, the layout bug will not occur.
