Ok, so the last report you mentioned #168244 is marked as a duplicate of #171795 which is the one Moini found. I can't make much sense of the detailed discussions, because it's over my head. Since the problem reported in #168244 is "Linked Image not Found" and the problem in #171795 is that the image appears but it's rasterized, it's hard for me to see them as even similar. But of course I have to trust the developers, since I don't understand.
If you're saying that #168244 seems to explain the results you're getting, then there isn't any need for me to try and reproduce it. But if you're still not sure, or you're seeing things not mentioned in the report, which perhaps should be mentioned, I think I understand what to do, to try and reproduce it. There hasn't been any new comment to #168244 in over 2 years, and just under 2 years for the other report. So if there is any new info that might be helpful, it would be good to post it there.
Do you still want me to try and reproduce, or are you satisfied that #168244 is the same problem you're seeing?
(It would also be reasonable the post a new comment saying something like 'this problem is still happening, and is a big problem for me - is there any new info I could provide to get work started to fix this'. Or something like that.
