Hi, I'm having the same issue on Plasma 5.26.3. Blender and GTK2 apps are affected. Also GTK3/4 apps when forcing the x11 backend by setting GDK_BACKEND=x11.

GTK uses XIDefineCursor if XInput2 is available and falls back to XDefineCursor in the other case. Anyway I'll try setting up a python-xlib sample reproducing the issue.

As Patrick pointed out, that's probably a different issue than https://bugs.kde.org/show_bug.cgi?id=420859 because the cursor is not correct even after rebooting

Sample C code exhibiting the issue

Attached sample C code exhibiting the issue. Should I open an issue in KWin GitLab?

Maybe just submit a merge request to fix it! :D

On X11, windows which do not have any cursor set default to the cursor of the parent. For toplevel windows, that means the cursor of the root window. That issue is actually a duplicate of https://bugs.kde.org/show_bug.cgi?id=442839; there Vlad Zahorodnii explains in detail why the root window has the Adwaita cursor theme.

I am not sure if it is same issue but wxgtk app prusaslicer also has this issue. I believe it uses GTK3 internally.
But it definitely runs inside xwayland and not as native wayland app because backend is hardcoded in the app.

Yep, it's that issue :) I hope I can make a fix for that soon ;)

I think I am also running into this [issue] (https://forum.garudalinux.org/t/gtk-plasma-theme-not-being-applied-on-wayland/27801/6) ? For me GTK apps do not use the theme specified in System Settings -> Apperance -> Application Style - > GTK application Style or my cursor theme; instead, using the default, Adwaita

It's fixed for me in Gentoo, but not on my NixOS install. My wife on Fedora is also still experiencing this issue. Makes me think there is some patch in the Gentoo repos that helps with this... Thoughts ?

it's also fixed for me on Arch Linux.

This then suggests that it may be config / environment related (I use the same home folder on my NixOS and Gentoo installs, but observe different behavior). Unfortunately, I've tinkered a LOT when it comes to cursors, but I will try to see if I can dig up some relevant configs.

Quick update: After some deliberation I've found that the apps that still had the adwaita cursor theme on my Nix install were all flatpak apps that didn't have proper read permissions for the ~/.icons folder. Granting them permissions solved the issue.

I'm going to go ahead and close this for now, feel free to reopen if anyone has an issue with a non-flatpak app, or a flatpak app that does have the proper permissions set.

This still affects me with non flatpak applications such as Vivaldi and lutris

@Andres did you confirm that the flatpak apps in question have read access to ~/.icons and/or /usr/share/icons (or wherever your cursor theme is located), and that their XCursor search path isn't being overwritten using an environment variable?

You can use Flatseal to check this, or KDE's built-in permissions system in System Settings -> Applications -> Flatpak Permission Settings

Like I said in the above reply, this is affecting me on NON-flatpaked apps such as Vivaldi and Lutris which is installed via my package manager (Pacman)

On my system, Vivaldi browser 6.2.3105.48 running natively on Wayland uses Adwaita mouse pointer.
However, Vivaldi running on Xwayland uses Breeze mouse pointer as expected. The same with Chromium.

I am also getting this issue on non-flatpaked apps. (Garuda) Annoyingly I swear I remember I found a fix before, but my drive got corrupted to hell because my memory started going out and I don't remember what the fix was exactly.

Now Chromium 122 and other browsers based on it respects the mouse cursor theme. Currently Blender from Arch repos is the only app that does not respect the mouse cursor theme on my system. But it runs natively on Wayland and this bug report is about Xwayland apps. I'm going to close this report as fixed.
