For a displayed equation, the height is artificially increased by a displayMargin() in InsetMathHull::metrics if it is a displayed equation and there is a preview. This extra height is not covered by the preview image and what one can see is the background as drawn by the MathHull inset. The color of this background should be either Color_mathbg or Color_background depending on whether the preview is shown or not. git-svn-id: svn://svn.lyx.org/lyx/lyx-devel/trunk@32560 a592a061-630c-0410-9148-cb99ea01b6c8
