Unable to change some preferences, like theme, after they've been changed once

[dave0003]

On Debian Bookworm, with both the AppImage and Flatpak, I have this issue.

If I try to change the theme, under Page Style -> Dark theme, I can change it to something else the first time. After that, I'm no longer able to change the setting.

Some of the other settings (but not all) also have issues getting "stuck" (like Appearance -> Accent color).

To fix it, I have to delete the .config file for lagrange and restart it. Then I'm allowed my one change again.

This vaguely rings a bell, although the issue I'm thinking may have been related to window event handling and not the configuration file.

After that, I'm no longer able to change the setting.

Could you describe in more detail what this means? Does the UI dropdown/buttons not actually work, or does the UI work but the rest of application doesn't notice the change? I take it that restarting the app causes the changed settings to go back to the previous value?

[dave0003]

After changing the setting the first time, the UI dropdown does drop-down, but clicking on a different highlighted setting doesn't select it. Restarting the app still keeps the setting from the first original change. To get the setting to reset to default, I have to delete the .config file.

If you launch the app with the --prefs-sheet option, does it change the behavior for the better?

No, --prefs-sheet doesn't seem to make any difference.
