Confirming opening the OOXML .pptx on Winodws with 6.3.0.4 and current master. While from PowerPoint 2016 a save as ODF results in correct looking text annotation to the upper triangle object.

So guess this is an import filter issue for the draw objects.

There is no "transparent shape", but that is a group. It has nothing to do with the problem. Ungrouping shows the same error.

The problem exists independent from pptx import filter.

I'll attach an odp-document with two custom-shapes. The left one is from our own set and therefore compatible to binary MS Office. The right one is from an OOXML shape, imported from pptx. The text box settings have anchor to center, the text alignment is horizontal and vertical center. The red rectangles mark the text area of the shape.

Error: If you enable "Autofit text", the text is shifted to the right.
Expected: The text keeps centered.
[The tool "Autofit text" is not included in the toolbars, you have to customize a toolbar to get it.]

In the example document, the error becomes only visible for the upper triangle, because the lower triangle is a freeform (custGeom) and its text area is entire width and height of the shape. Therefore the text fits into the text area. In the upper triangle the text does not fit into the text area. In both cases the text area has a right/left inset of 0.1inch and a top/bottom inset of 0.05inch. For the upper triangle it is the default value, for the lower triangle it is set explicitly. For both shapes "normAutofit" is set, which corresponds to our "Autofit text on".
