Could you share a screenshot of the timeline in Immich? A screenshot of the thumbnail in the phone's local gallery app would also be helpful.

My bad, I thought I already uploaded it

What format are the images in? Would you be able to share a sample image?

[N8-Yue]

They are screenshots, downloaded images or sent images. Basically anything that contains text suffers from this issue. This image here is blurry for me so I upload it

The issue is still not completely fixed, some files now look as intended but some files are still very blurry

Do you mind sharing a .zip with a few images that still have very blurry thumbnails? I have a potential fix, but I'd like to confirm it resolves the issue.

I downloaded a couple photos that are affected. What I also noticed (a different issue) is that some photos are shown at a different date on the web compared to the mobile app. Some photos that are stored locally and on the cloud are e.g. shown on the 12th of August while on the web the same photos were listed under the 11th of August.
