after upgrading to Nextcloud 19, I saw weird behavior on preview generations.
I’d like to know if someone else saw it too.
One issue is that it generates previews for all files (also .pdf which should not be the default behavior from what I know…). Even if my config file contains:
I get previews not only for images. Shouldn’t I get previews only for those 3 types of file?
Another issue is that the web client doesn’t find some previews when loading a folder and it gets stuck untill the 404 timeout on that failed get request, actually not showing the folder list for 10 or more seconds. I don’t know yet why some previews are actually not available…
Ty for your answer, @Ferdinand.
Actually my problem is that, even if I delete all previews, when I enter a folder with .odt, .pdf, etc. files the thumbnail gets created again, in spite of my config file, as shown above. It doesn’t happen on Nextcloud 18.
That wouldn’t be a problem in general since I always wanted all kinds of thumbnails so far, but it looks like with Nextcloud 19 another issue comes up, that is the fact that sometimes a preview is not found (404 error on Firefox developer console) but this 404 arrives after many seconds so the page is shown after 10-20 secs when one of these previews in not found, and that’s quite annoying. This last issue could be due to my system, that’s why I asked if anyone saw it, or it’s only me.
