Affected app version

1.1.3

Affected Android/Custom ROM version

Android 14

Affected device model

Xiaomi Mi 11 Ultra

How did you install the app?

F-Droid / IzzyOnDroid

Steps to reproduce the bug

1. Open a raw dng file
2. Compare the raw file with the jpg version if available
3. Or compare the raw file with another gallery

Expected behavior

The dng file should not look blurry. Also, when deep zoomable images are enabled, I would expect to be able to zoom into the dng file just as much as the same jpg file with the same resolution.

Actual behavior

The raw files from my camera and from my smartphone (dng format each) are blurry if I view them in the Fossify Gallery. Also I can not zoom in as much I can in the jpg version.

Screenshots/Screen recordings

Additional information

I had to zip the dng file because of upload restrictions (no dng files allowed). I noticed that I can zoom in less in larger dng files (those from my camera) than in smaller dng files (those from my smartphone). Larger dng files look far more blurry (see second screenshot).
