NEW per last comment.
Comment 4 Buovjaga 2019-11-08 19:20:58 UTC
You are using linked images in the file, so we cannot test. Do you get the same result, if you use embedded images (which is the default way)?
Comment 5 Grantler 2019-11-10 08:39:01 UTC
I regularly use linked images because of "cascading" some effects from other image processing programs. If details of one image (not of each one) are altered the generated new image (export) can contain this alteration.

Problem seems to be solved on LO 6.3.3.2

BTW:
Today I checked once more on LO 6.3.3.2: No faulty results any more (linked or embedded images did not matter)! (OS LinuxMint 19.2-64 Mate)

Thanks a lot for repairing that function!
