When using this setup, the Implementation type resets itself to Xdg-Desktop, but im using gnome. And at the IDE Theme the Dark theme resets itself to Dark instead of Monokai Pro.
Im using latest version of gnome, intellij and the plugin.
Can you check the logs whether there is something related to auto dark mode. Also can you provide the settings xml file of auto dark mode?
Possible causes are:
Something gets wrong during serialization.
Something is wrong with loading the required native library.
In both cases the xdg-desktop implementation is choses as a fallback. As you have said that the selected theme also isn't saved for you I suspect some settings aren't properly stored.
