It is indeed unfortunate that this is happening. This issue goes all the way back to flight simulators of 2006 and possibly before, and while this simulator seemed to have sorted it out, the morphing and other notorious terrain glitches made their grand return with the USA World Update.
As said above, it was brought to their attention in two Q&A sessions in a row, and they don’t seem to be particularly alerted, but the latest Feedback Snapshot says it is under investigation after so many months of this issue getting ignored. But there are a couple ways you could help:
- Send a Zendesk report. Asobo have made it clear that when prioritising visual/cosmetic issues that aren’t game-breaking, they rely on the amount of times it is reported. As such, the more reports they get about this, the quicker they’ll start taking care of it. I saw this happen with the flickering clouds several months ago.
- Upvote this thread. You can do so by clicking the blue “Vote” button at the top of this thread, right next to its title. It also helps to keep it alive with new footage or discussion around the issue’s status (threads are automatically locked after 30 days of no replies), but bumps are not allowed.
