v27 - download view - new jpegxl file - thumnail on file is black [Fixed]

Post by masterjp »

I converted a jpeg file to jpeg xl format.
The source and destination folder was the download folder.

I do not see a thumbnail of the destination jpeg xl file in download folder.
A swipe down does not refresh something.

I will see the file in xnview if I open it in device memory view.

If I switch to device memory and the download folder, I will see a thunbnail on the jpeg xl file.
So I think the download folder thumbnails do not correctly refresh.

I did the test again.

I converted a jpeg file from download folder (internal smartphone memory) to the same folder as jpeg xl 80% compression.
In gallery and folder view I see the filename and filesize, but the thumbnail is missing.
I can open the jpeg xl file in gallery and folder view and the picture is visible.

All jxl files have no thumbnails or only these ones?

I also don't see JXL thumbnails when entering from some views. Only when entering via “Folders” and "Device Memory" I see these thumbnails.

On my Samsung device (Android 16) I do not see any thumbnails of jpeg xl files. So it is a general problem of all jpeg xl files.
