SUMMARY On X11, cursor theme is applied as expected to GTK3 apps installed via flatpak. But on Wayland the same apps always use Adwaita cursor theme. STEPS TO REPRODUCE 1. start Wayland session 2. make sure your current cursor theme is NOT Adwaita in system settings > cursors 3. install any GTK3 app via flatpak/flathub (I installed pulseeffects, Transmission torrent client and Rhythmbox music player) 4. open the just installed GTK3 app and hover over it OBSERVED RESULT when we hover over the GTK3 app, cursor changes to Adwaita theme. EXPECTED RESULT GTK3 apps installed via flatpak should respect the cursor theme set in system settings > cursors when running on Wayland. SOFTWARE/OS VERSIONS Operating System: Arch Linux KDE Plasma Version: 5.18.3 KDE Frameworks Version: 5.68.0 Qt Version: 5.14.1
Is this something we can set with xsettings maybe?
(In reply to Nate Graham from comment #1) > Is this something we can set with xsettings maybe? Xsettings, as far as I know, is for X11 only.
Cannot reproduce on latest KDE Neon Unstable. Could you reproduce?
Tested these gtk3 apps from flathub: PulseEffects News Flash Transmission torrent client HandBrake Celluloid Rhythmbox Swell Foop When I use Breeze cursor theme, the problem is still happening but currently it is random and harder to reproduce. Generally it occurs when I open the app for the first time after login to Wayland session, and the app uses the correct cursor theme after it to be restarted 1 or more times. When I use a third-party cursor theme like Night Diamond (Red) from https://store.kde.org/p/1295073/, the problem consistently affects almost all GTK3 apps mentioned above (only handbrake and Transmission always use the third-party cursor theme on my system). Operating System: KDE neon Unstable Edition KDE Plasma Version: 5.19.80 KDE Frameworks Version: 5.73.0 Qt Version: 5.14.2
Thanks for the information!
Any progress on this?

I have added XDG_CURRENT_DESKTOP=KDE:GNOME to /etc/environment file and the bug persists even after re-login.

I have followed the instructions in your link but adding [Service] Environment="XDG_CURRENT_DESKTOP=KDE" No change. Cursor theme is still not respected by some GTK3 flatpaks. Thanks for your help anyway.

Created attachment 135846 [details] Video guide!
Thanks for the video. That's weird because sway is not even installed on my system. I have tried using "sway" anyway but the problem persists. I'm using red variant of Night Diamond cursor theme ( https://store.kde.org/p/1295073/ ) and Rhythmbox music player from flathub in my tests.

Some portal is deciding to start or not xdg-desktop-portal-gtk based on XDG_CURRENT_DESKTOP env, if it contains "KDE" portal will not be started, if "sway" or "GNOME" it will be started. >I'm using red variant of Night Diamond cursor theme Custom cursor themes in flatpak is another problem https://github.com/flatpak/flatpak/issues/709
Thank you for clarifying :) Currently Breeze cursor theme is correctly applied to gtk3 flatpaks installed on my system even without the instructions from flatpak bug report. I'm giving a more accurate title to this report right now. Flatpak in general is still a mess with annoying bugs. :(
Still an issue. Tested Rhythmbox music player and Celluloid video player from flathub with Radioactive cursor theme from flathub. Operating System: KDE neon Unstable Edition KDE Plasma Version: 5.24.80 KDE Frameworks Version: 5.91.0 Qt Version: 5.15.3 Graphics Platform: Wayland
This bug persists on neon unstable. Workaround: 1. install Flatseal from flathub and open it 2. select your gtk app 5. scroll down to 'Filesystem' section 4, enable 'All user files' However, this does not work with all gtk apps. Audacity and Deluge torrent client, for example, are still using incorrect mouse pointer. Operating System: KDE neon Unstable Edition KDE Plasma Version: 5.26.80 KDE Frameworks Version: 5.100.0 Qt Version: 5.15.7 Graphics Platform: Wayland
The error still exists. Arch Linux, Plasma 5.27, Frameworks 103, Wayland. The solution from soredake worked right away, but I think this error is unacceptable. Link to the solution https://github.com/flatpak/flatpak/issues/2861#issuecomment-742421920
This seems to be reverse in Plasma 6 Wayland: I have the correct cursor in Gtk windows (Firefox, Inkscape, Easy Effects), but the wrong one in Qt windows (Kile, Tokodon).

Can reproduce with Tokodon from flathub. File a new bug for Qt apps please.

Found out solution (at least for me) from Arch Wiki: (https://wiki.archlinux.org/title/XDG_Desktop_Portal#Poor_font_rendering_in_GTK_apps_on_KDE_Plasma). Run the command: "/usr/lib/xdg-desktop-portal --replace". It requires to xdg-desktop-portal-gtk to be installed. I ran this command once, and now every flatpak GTK app works corretcly with cursors, even after reboots.
