@Ashley, I know man, but It just started happening out of the blue.
Now, I don't know what is going on with it tbh. It's just clipping once at the beginning of layout and moves position of the pinned image. I have toggled all of the events in the event sheet ( except "On layout start" ) to see if its something I've done, but it's still happening, so I'm assuming it is a bug.
To see this weird clip go to layout "Game test" and play it. The detector ( green box ) is being spawn at origin point of the red box, which is located at the bottom of the image. Then it's pinned. Once that happens the whole picture clips for several milliseconds and the green box suddenly is attached to the middle of the image.
