RDM Flatpak v2025.2.0.8; Websession Auto Fill Not Working Reliably

Hello,

some time ago, I migrated from another product to RDM on Windows with around 331 entries and was very satisfied with it. Recently, I switched to the "Fedora 42 Workstation" operating system and unfortunately found that RDM as a Flatpak (I also tested the RPM version) doesn't run as smoothly as the Windows version.

I understand that the Flatpak version might not be as fully featured (e.g., Rustdesk is missing) as the Windows variant, but I had assumed that features that are implemented would work at least as reliably as they do on Windows.

In my case, the SQLite database was fully created and maintained using the Windows RDM version. Unfortunately, in the Flatpak version, AutoFill or AutoLogin doesn't work for many web sessions. The form fields are correctly identified via "Discover", but when opening the session, nothing happens — the values are not entered into the fields. These same web sessions all work perfectly fine on Windows (with Edge as the engine).

I hope there is a solution for this or that the issue will be fixed in a future release. RDM is one of the tools I actively use for many hours every day.

Two example applications that may be familiar:

Example "Portainer" (Autologin does not work)

Example "Proxmox VE" (Autologin works)

Could the issue possibly be resolved through a configuration adjustment? Is there any way to change the web engine being used, maybe to Firefox or Edge Chromium? As far as I know, WebKit is fixed.

Thank you very much.

Best regards,
