I've been getting an issue reported by other users where the Radeon Settings keep telling me an update is available when I'm already on the current stable/recommended version. I gave up and upgraded to the next one up the other day and switched on this evening to be told there was another update available.
Thing is, I'm on 19.1.1 and it's telling me that there's an "upgrade" available to 18.12.2. That... doesn't make sense. That's a downgrade. Also, the version in the tooltip doesn't correspond to the version number listed for update (see screenshot).
The 19.1.1 update was done using a clean install, as I always do.
