Without the document it is very hard to investigate. Please reduce the document (remove slides) as far as possible, but so that the problem is still visible, and provide a download. (I guess, it is a wrong set image filter. But without document...)

Since it's a university document, I don't think I can legally put it here. It's on every slide. At first I though it was something like read-only, but I can modify. And when I try to copy the text and I select it, it keeps that grey thing. Picture on fist post

I have seen differences between pptx and odp in the interpretation of image filters. I mean the settings from the "Picture" toolbar, especially the sublist "Color". For LibreOffice the values should all be 0, but 1.0 for Gamma. Another think to do: Unpack the original file and look, whether the original pictures are correct. Same for file saved with LO. I think of pictures, because the slides look as if they use a background picture.

Could you post a ODP without content? What is happening on the "Master slide"? Also, it looks like the background changes between slides 8 and 9 in the second screenshot; have you tried removing any background? (For diagnostic purposes, at least!)

I unselected "display the master background" and it's gone, but I have to do it for every slide. I made the background as blank and it worked Guess the teachers do stuff differently in some pp thanks

It looks like a moiré effect, so perhaps the master slide has a texture / pattern in the background?
