Created attachment 191359 [details] Examples for testing Open attached document. It contains a comment, a Math object and two text boxes, one of them with rounded corners. To get rounded corners of a text box, move the mouse to the left-top corner of the text box, so that the mouse pointer becomes a finger. Press mouse button and drag the handle to the right. The handle for rounded corners is a little bit larger than the resize handle. Click on the Math object. Set 'point edit mode' to on. You can see the same handle as in case of the text box, but you cannot drag it. Click on the text box with rounded corners. Click on 'Clone formatting' and then click on the Math object. You can see, that the handle has moved. But the corners do not become round. I guess, that it is intended, that rounded corners do not work for Math objects. In that case, the 'point edit mode' should not be possible for Math objects. In case rounded corners should work for Math objects, the handle behavior and the rendering need to be fixed.
Confirmed. Alternatively, using the 'Position and Size' dialog 'Slant & Corner Radius' gives direct control for Drawing objects. But the dialog the OLE frame for the Math object shows the 'Corner Radius' and slant 'Angle' as unavailable. While it is held in a frame, the formula is not a drawing object like the text boxes. The frame holding the formula can be styled (area bg fill, frame line color, centering) but since it is not a draw object kind of seems reasonable to not be able to apply a radius or slant to the object. Kind of a recasting of bug 99792? So not anything new...
