The issue you are facing:
So, i’ve been pulling the little hair i have left trying to figure out why my desktop PC are not showing any thumbnails for .heic files. It works fine on my laptop which uses the same OS and browser (firefox on debian)
Turns out it’s related to scaling in the browser!
When i open a folder full off heic pictures i see nothing but the stock grey no thumb image. If i increase the zoom in firefox to 110% and refresh the page; voila! the thumbs work perfectly fine.
Looking at the requests i see that when i run 100% zoom it’s full of error 400s, bad request. Zooming in and it looks fine.
The difference being that when i run 100% zoom - if fetches thumbs in the size of 250x250, zooming in and the thumbs requested are 500x500. For some reason the nextcloud app is not able to serve the thumbs in 250x250. My desktop screen is 3440x1440 so it makes sense it wants lower res thumbs.
Note. This only happens in “Files”. Photos and other apps are OK.
Note Note: Other formats work fine. It’s only HEIC that has this issue.
Is this the first time you’ve seen this error? (Y/N): Yes
Steps to replicate it:
- Have a 3440x1440 monitor
- Open heic folder listing in “Files” in we browser
- Change zoom from 100 too 110% and refresh
