SUMMARY

I have a directory full of files downloaded with youtube-dl. When downloading a new video, youtube-dl keeps creating and deleting temporary files. I can see the files being added/removed every second or so in dolphin when the files being downloaded are in the files currently visible. This is fine.

The problems is when I scroll down in the list to a point where all files are older files that are not changing, the file lists jumps up and down by one row every second or so due to files added/removed outside of the currently visible files. This very annoying and makes it difficult to select files I want to work with.

STEPS TO REPRODUCE
1. Create a directory containing a lot of files (eg 2 or 3 times the number of files visible at any one time in dolphin)
2. Run something that keeps adding and removing temporary files in this directory (I use youtube-dl)
3. Sort by recently modified so the files added/removed are at the top of the list.
4. Scroll to top of view. The files continually added/removed will be seen.
5. Now scroll down so the files being added/removed are no longer visible.

OBSERVED RESULT

The file list jumps up and down a row due to files added/removed above the currently visible files.

EXPECTED RESULT

If the currently visible files are not changing and the changes to the directory are outside of the currently visible files based on the sort order, I would expect the list to remain static.
