Qt flatpak app (KeepassXC) does not follow system cursor theme

Help

Using Fedora Linux 41 KDE Plasma on wayland, with latest updates, Plasma 6.2.5.

KeepassXC (Install KeePassXC on Linux | Flathub), when installed from flathub will not follow the system’s cursor theme when changing it. To my knowledge, it’s the only flatpak app that does this. Fooyin (Install fooyin on Linux | Flathub) behaves as it should.

KeepassXC has an issue related to this but it is a little bit old: Linux & Wayland & Flatpak - cursor gets changed back to default when hovering over keepassxc · Issue #11108 · keepassxreboot/keepassxc · GitHub

I was able to reproduce this issue using the preinstalled Breeze Light cursor theme.

How to reproduce:

Make sure you’re using Wayland Plasma session, install KeepassXC from flathub (it is an officially supported method of installing the app: Download – KeePassXC listed under “Other Official Linux Packages”), change cursor theme to any other than Breeze and open the app, the cursor should change back to Breeze.

In the linked issue a contributor to the project said this was a KDE issue, so that’s why I’m posting this here. What’s weird though is that no other flatpak app does this (that I tested anyway). If anyone more knowledgeable than me has a solution, I appreciate it! Thanks for your time!

Hi - this appears to be an existing issue with the KDE Flatpak runtime and how it interacts with Flatpaks using Qt version 5 (as KeepassXC does) as opposed to Qt version 6 (like Fooyin). The open bug report is located here: 482805 – In Plasma 6, custom cursor settings aren't affecting KF5 Flatpak apps

There was a change merged in an attempt to resolve, but it looks like it’s not quite there yet: Update some modules, hopefully fix incorrect Breeze cursor style (!211) · Merge requests · Packaging / Flatpak KDE Runtime · GitLab

If you’d like to keep up with updates to that bug, you can add yourself to the CC list in Bugzilla to get email notifications whenever new comments are added or the status is changed :slight_smile:

That CC list checkbox is located here - making sure that’s checked, then choosing “Save Changes” will add you:
