Description Fernando Marcelino Muniz 2026-01-20 20:10:00 UTC

STEPS TO REPRODUCE
1. Have a couple of videos on Desktop.
2. Open the Desktop folder on Dolphin.
3. Compare the thumbs.

OBSERVED RESULT
Some have one thumb on Desktop and another on Dolphin.

EXPECTED RESULT
They should look the same, using a single thumb, so they don't waste space unnecessary.

It doesn't only happen in the Desktop area.
If moved a video file inside a folder, and inside the folder the file had a different thumbnail.
