Important MUI related note:
If you can not see GUI elements because the background is showing through you must modify your MUI preferences so that the color settings are not set to "same as parent object". Set to a light grey color or other neutral setting.

Specifically:
MUI->String->ReadOnly
MUI->List->Container
MUI->Group->Container
etc.
