I just reinstalled, and with the first boot of the new system, cursor still does disappear on the borders Croeso window. And cursor is bigger. I recorded the video with my phone, to avoid making changes to the system, if you need proof.
With second launch, the only change I made was to mark the new empty session. And cursor has stopped disappearing and is smaller.
The first run contains a saved session from Live mode?
I always changed the appearance on the first startup, so I thought it was the fault of the Midna, but it seems to be a problem in the saved session.
