Please see the undermentioned:

I thought that this was a problem with the OS (hence the post over there), except that despite this occurring to xdg-desktop-portal-kde-6.3.4-2, it doesn’t to xdg-desktop-portal-gtk-1.15.3-1 (as evaluated with about:config’s "widget.use-xdg-desktop-portal.file-picker": 2 in firefox-137.0-2). [1]

I think that this is a bug from an update, so I’ve filed bugs.kde.org/show_bug.cgi?id=503430.

Just to check, is your phone mounting to a location that’s indexed by baloo?

@johnandmegh, clever! I don’t believe so (I think they’re default):

Additionally, although I didn’t know it when I created that post, I don’t need to enable filesystem access to the smartphone for it to slow all filesystem operations. It reproduces with it set to merely charge.

    Part of the initial slowdown in dolphin-25.04.0-3.fc42 correlates with KIO outputting a QLocalSocket::PeerClosedError:

    Although it correlates immediately, reproduction isn’t consistent. It’s a symptom.

    Likewise, for xdg-desktop-portal-kde-6.3.4-2.fc42.x86_64:

    However, this might more broadly be a bug with Flatpak. [2] [3]
