Google also shows it like PowerPoint does.

The "number%" are just text with character background color and the % having superscript formatting, in a textbox. Seems like this is not a PPTX issue: ever since it is possible to set background color to text in textbox in Impress (LO 5.0), the background color is painted to cover only the height of the smaller subscript / superscript characters and not the full height of the normal characters. Let's focus on this here. There are two more problems: - in master, bug 168835 shows that there is now a lot more superscript characters than needed - painting looks like two separate boxes with an unpainted vertical line between them, but this is only with certain zoom levels (for me: 100% OK, 90%, 80% NOK, 75% OK, 65% NOK, 60% OK, 55% NOK, 50% OK, 110% 120% 130% NOK, 140% 150% OK), so some sort of rendering glitch. Let's hope this can be made unseen with painting all characters to the same height level as normal characters, this is scary.
