I bring this up here because KDE peeps don’t seems to find this reproducible but I find it is consistently reproducible for me using the steps above with Fedora 43 Kinoite.
It doesn’t reproduce on my F42 with KDE Plasma 6.5.2. (Folder view widget for ~/Downloads, touch ~/Downloads/test shows up immediately).
It did reproduce on Kinoite 42 and also on 43 after rebasing. I then investigated some more, the folder view widget didn’t show any files in the ~/Downloads folder that I pointed it to, neither existing nor newly created. When I pointed it to /var/home/$USER/Downloads, the files showed up. So I think this is some kind of bad interaction between the widget and the way that Fedora Atomic mounts the user’s home.
I confirm that pointing the widget to /var/home/... instead of ~/Downloads works as expected and automatically shows new files.
I guess it’s a Kinoite thing.
But then, did you try with creating a second user, @l-c-g ? Curious why there would be no issue in that case? Might their home directories be mounted differently?
Very cool find, by the way. Thanks for this. At least we have a workaround.
