Nothing more to add here, except just to say I’ve voted for this to be fixed. I’m big on VFR and taking photos while I fly, so in cloudy/dark conditions, it’s a big deal for me. Of course, I could just fly in midday, relatively clear conditions, which seems to minimize it.
Perhaps there’s an anti-alias setting which can help? Hope it can be fixed soon. In the MSFS World, it’s not just clouds that have a silver lining!
