SUMMARY
***
Cannot order files on the desktop, plasmashell reports "Too many files", but there are only ~70 files.

sudo journalctl -p 3 -xb
Sep 13 19:54:15 neuromancer plasmashell[1422]: org.kde.plasma.folder: Greater than 4096 files and folders on the desktop; this is too many to map their positions in a performant way! Not adding any more position mappings.
Sep 13 19:54:15 neuromancer plasmashell[1422]: org.kde.plasma.folder: Greater than 4096 disabled files and folders; this is too many to remember their position in a performant way! Not adding any more position mappings.

find ~/Desktop/ |wc -l
87
***


STEPS TO REPRODUCE
1. Copy more than ~20 files on the Desktop
2. Arrange the files
3. Reboot

OBSERVED RESULT
All files cluttered on the first (of two) Displays, ignoring their original place on the desktop

EXPECTED RESULT
Files stay where they were put.

Hmm, it must be counting the mappings that have been growing infinitely, not the actual number of files and folders on the desktop.

Comment 2 Harald Sitter 2023-09-24 12:24:00 UTC

The warning is about mapping data, that does by design include **currently** inactive mapping data. Active or not they get evaluated/toggled when screens attach/detach so they negatively impact performance.

https://invent.kde.org/plasma/plasma-desktop/-/commit/685fac5355812cfce67c4008c38fa3fbf5f75b08 should ultimately fix this by removing the excess files that got accumulated by the actual bug underneath this all.

I just wanted to use the comment section of this bug to say thank you Harald and Nate (and all the rest of the project) for your wonderful work! Thanks for fixing my issue, highly appreciated!

Comment 5 Nate Graham 2023-09-30 18:24:36 UTC

You're very welcome! To clarify though, the actual work was all done by Harald and Marco. At most, all I did was some bug triage and merge request review. :)
