Description Timothée Ravier 2023-09-22 13:50:41 UTC
GTK settings are not used by applications in KDE sessions.

See: https://pagure.io/fedora-kde/SIG/issue/396

This is likely due to the upstream change: https://github.com/flatpak/xdg-desktop-portal/issues/1017

Reverting to https://bodhi.fedoraproject.org/updates/FEDORA-2023-8a95627f94 "solves" this issue.

Reproducible: Always

Steps to Reproduce:
1. Install Fedora Kinoite 39 (beta)
2. Install a GTK based application from Flathub (Celluloid for example)
Actual Results:  
Fonts are incorrectly displayed, maximize buttons are missing, cursor size are wrong

Expected Results:  
Fonts, maximize buttons, cursor size are reasonable defaults

Comment 1 Fedora Blocker Bugs Application 2023-09-22 13:53:40 UTC
Proposed as a Blocker for 39-final by Fedora user siosm using the blocker tracking app because:

 This is breaking basic display settings for GTK based Flatpaks in a KDE session.

Comment 2 Geraldo Simião 2023-09-23 14:09:41 UTC
This happens too on a upgraded F38 -> F39 KDE regular rpm spin.

Comment 3 Geraldo Simião 2023-09-23 14:56:18 UTC
At the RPM F39 kde (upgraded from f38) the workaround for me worked fine:
sudo nano /usr/share/xdg-desktop-portal/kde-portals.conf
added gtk to the default line:
default=kde;gtk

Don't knoe if this works for flatpaks too, maybe not.

Comment 4 Jonas Ådahl 2023-09-25 08:41:32 UTC
> Don't knoe if this works for flatpaks too, maybe not.

This will work, and should probably be made a change upstream in KDE unless either KDE emulates what gtk needs from org.gnome.* GSettings, or the decision to not pull in all settings backends despite portal config file not listing them is reversed.

Comment 5 Geoffrey Marr 2023-09-25 23:41:38 UTC
Discussed during the 2023-09-25 blocker review meeting: [0]

The decision to classify this bug as an "AcceptedBlocker (Final)" was made as it violates the following criterion:

"... the desktop environment must perform regular operations like windows close/resize/maximize/minimize/fullscreen (when supported/applicable)..." in the case of OOTB-installed GTK applications, e.g. Firefox.

Comment 6 Matthias Clasen 2023-09-26 14:59:41 UTC
Timothee, did you try the suggestions in the upstream issue?

My understanding (and I've warned about this before the upstream change was merged) is that KDE needs to ship a portal configuration file that makes the settings portal use both kde and gtk backends, and the KDE spin needs to pull in the gtk portal backend package.

Comment 8 Timothée Ravier 2023-09-27 17:27:43 UTC
I pushed the merge button on https://invent.kde.org/plasma/xdg-desktop-portal-kde/-/merge_requests/231. We'll backport it to 5.27 and our packages.

Comment 9 Timothée Ravier 2023-09-27 17:36:56 UTC
5.27 backport: https://invent.kde.org/plasma/xdg-desktop-portal-kde/-/merge_requests/233
