Often when I stop the player in the Editor, I get errors (listed below) spamming the console continuously until it reaches 999 messages. I can't see anything in the stack trace that is related to my own code though so I don't know how to resolve them. They seem to refer to gui objects so I'm not sure if it's linux related problems or my own code causing delayed problems.
If I can hone in on what's causing them I will. Atm I can't see any pattern to when they occur and they come and go within the same session.
