When designing the form and when adding a new item, the multi-line text has a white background, however in the List Form WebPart it takes the background colour.

Glad to have helped, if you could mark off my answer as correct I'd appreciate it.
When you are in the designer, select your multi-line text box control and then use the "Background Fill Color" (the little paint bucket icon) and explicitly select the color white. Once you publish your form, see if that fixes the issue you are running into. Normally the multi-line text box assumes the background color of the form in view mode and this will cause that to be overridden.
Thanks Mike, but would need to do this for all fields and it isnt such a good look.
Done some testing with the the Single Line of Text Box. The Single LIne text Box displays as expected while the Multi-Line Box displays with the back ground colour
I have tried with multiple browsers so can eliminate this as being a cause. Seems to be how the Webpart renders the Multi-Line Box.
You should only have to do it on Multi-line textbox controls. Most of the other controls as you have seen render their backgrounds properly. You could also try adding some CSS to the form to see if that will solve the issue.
The workaround works and with some tweaking of the box size and the font colour (just to make sure). it is fine.
Hopefully there will be a fix for the cause ofthe problem, not just the symptom.
