--- Comment #13 from Kees-Jan Timmer <keesjantimmer at gmail.com> ---
Using:
Versie: 6.2.2.2 (x64)
Build ID: 2b840030fec2aae0fd2658d8d4f9548af4e3518d
CPU-threads: 4; Besturingssysteem: Windows 10.0; UI-render: standaard; VCL:
win; 
Locale: nl-NL (nl_NL); UI-taal: nl-NL

This bug is still present.

1. Create a new presentation.
2. Insert a .jpg picture on a slide
3. Set Transparency of the picture to 75% (or whatever..)
4. Save file as .pptx
5. Exit LO
6. Reopen file with LO
7. Transparency is gone.

btw, maybe this is Related? 

Change Brightness or Contrast of a picture.
Save as pptx.
Reopen file.
The slide opens with the picture in the right brigtness/contrast, but the % of
brightness and contrast are both set to 0%.
So the original picture is gone, and you cannot return to the original picture.

btw. Saving as .odp and reopening .odp.. Both brightness%, contrast% and
transparency% are retained correctly, and you can easily return to original
picture.

But I have to cooperate with people who are using pptx's....
