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:
‘enabledPreviewProviders’ => array ( 0 => ‘OC\Preview\PNG’, 1 => ‘OC\Preview\JPEG’, 2 => ‘OC\Preview\GIF’, ),
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…
