Condensation Screen RIDER 400
What I can add to this is the problem is still there in the 550.
My 400 drowned back in March 2020. On a very wet ride the screen was very foggy, but still readable. After a couple of hours the screen went white (backlighting) I turned it off and on again and it stayed off. Would not restart, it had finally given up the ghost.
I replaced it soon after with a 550. Now 18 months on and on a ride this winter during one of our short spells of relative freedom (I live in Melbourne Australia) I noticed the screen had a small area that had misted up. I guess this one too will eventually die.
My partner also has a 550. Funnily hers which lives in the open on a naked bike has never fogged up
