Created attachment 202376 [details] A text box with some trailing empty lines The attached PPTX has a text, which is set to auto-shrink text on overflow; after "textbox" paragraph, there are two more empty paragraphs. There is also a line shape, positioned to strike out the last empty paragraph. This means, that the "textbox" paragraph is positioned significantly above the horizontal line shape. Opening it in Impress ignores the empty paragraphs; the result is, that the line shape strikes out "textbox" string.
