The 'SetBackgroundColour' method doesn't appear to function.

Hi,
This was answered in

text output with transparency off, which demonstrates how the new background colour is drawn.
Any change to background colour is only visible on the next draw, the existing background pixels do not change until then.
In other words, the 'SetBackgroundColour' only changes the background drawing colour,
to be actioned on the next drawing function,
it does not have any affect on the current screen pixels.

The screen does not actually have a background as such, it's just what colour the pixel was drawn with, foreground or background colour.
