If you have already installed 2.3.1 beta and you are getting
Variable unknown_object.buffer_surface_copy(103476, -2147483648) not set before reading it.
you will need to open the "GMLAPI" script and remove (e.g. via Ctrl+H) the following two snippets:
"buffer_surface_copy", buffer_surface_copy,
this mini-fix will be included in 1.0.27
