This pptx [originally MSO generated, having Calibri font] has text displayed differently when opened in LO even when substitute fonts [Carlito, since I don't have Calibri] have same metrics. Due to same metrics, it should have been exactly similar, I expected.

See that at the end of one/multiple lines, one/few words either have been pushed to next line or extra words have been included in the line.

I'm uploading this side by side comparison for only few of the slides via gif

This isn't a matter of substituting font, even on the same system with the same fonts the text layout in text boxes is different.

What's interesting is that the PPT of the same presentation is shown almost perfectly identical, except the title on slide 3 (and a small issue on slide 5).
