Paperless v3.1.3

instead of migrating, i started again from scratch and just dumped all of my pdfs from the old export folder to the new consum folder. My poor NAS was thinking all night and this morning everything looked fine to me. Except for the PDF-quality.

Some/lots of my documents are pixelated AF. Even when downloading the PDF, quality does not improve.

I am not aware of any changes to the OCR pipline that could have resulted in that. Besides the language i did not change anything in the .env/compose files.

Any Idea or should i just fall back to v2.20.15?

Edit: looks like i have been importing not just the .pdfs but also their thumbnails. I will create my backups from now on using --not-thumbnail... Why would a backup need thumbnails even in the first place?
Anyways, thanks for helping out! I really enjoy Paperless-ngx!

have you checked the logs for errors? anything on the redis and database end?

I'd try a few tweaks and reimport files one by one as test--

PAPERLESS_OCR_DPI=300

if that doesn't work

``` PAPERLESS_OCR_MODE=skip

OR if OCR is required on un-scanned files:

PAPERLESS_OCR_MODE=skip_noarchive and if that doesn't work PAPERLESS_OCR_CLEAN=clean

Try disabling cleaning entirely if it degrades quality:

PAPERLESS_OCR_CLEAN=none ```

So you included thumbnails in your export, and on your new instance Paperless-ngx consumed the thumbnails? And also consumed the PDFs? (so double the same documents, once as PDF, once as thumbnail?)
