Viewport_2d_in_3d - screen_size issue when using with ArrayMesh

[DigitalN8m4r3]

the project am working on requires a non flat surface/ non godot built in to be used for the viewport2din3d screen
now when i try to use it that way, i get the following error

Invalid set index 'size' (on base: 'ArrayMesh') with value of type 'Vector2'.

this can be fixed by simply adding a bool that indicates if this is a ArrayMesh or not
