What do you mean by regen? I’ve so many of those black lines, it’s killing the fun.
Yes the water looks ugly with DLSS, like a bad video compression.
My question too.
I’m beginning to think and imagine seeing those black lines when I fly in other flight sim products too.
I also get this all over the world, wish they can get it fixed.
It might help if everyone post their PC specs. I have Windows 10 Pro, 32 GB RAM, GTX 1080, and lots free space on my MSFS drive (NVMe).
They definitely can get them fixed since the issue wasn’t happening before.
We just have to vote and wait. 
Guys, try this. In MSFS’ General Options screen or page, and in the Graphics section; set “Global Rendering Quality” to “Ultra”.
Post your PC specs and let me know if it also helped you.
I already have everything on Ultra and I see the black lines everywhere. 
I still have them also but not as much. It’s tolerable now. This seems to be working fine with me. Try comparing your settings with mine below:
The only thing that seems to remove the lines for me is to disable photogrammetry.
Hmmmm… plagues Hawaii too.
Island hopping ? Follow the black lines in the ocean.
Immersion killer.

Same here. Completely kills the immersion like you said. Hard to get motivated to fly the islands when you know you’ll have the lines everywhere.

Shame as the island are done really well.
Black lines are present for years.
The black lines do seem very prevalent in the sea around the Hawaiian islands, which is very disappointing considering this was the subject of WU13. But maybe not to do with that, more to do with something in the graphics engine in MSFS which has clearly never been fixed.
Yup. Noticed it on approach into Maui. Looked horrible.
Same around Mariana Islands.
It’s definitely not related to graphic settings as this bug appears only in some remote places. I don’t see it on English Channel or Baltic Sea.
I still see those black lines absolutely everywhere.
Yes this issue is very disappointing
Someone asked about this during the Q&A portion of the developer’s stream, but the question was not answered. Perhaps it’s another issue similar to the horizon line which appears through mountains and can’t be rectified with this build, but we have no way of knowing without any sort of response. We don’t even know if they are aware of the issue or not.
I’m not sure why this issue only has 101 votes atm but I’m sure that plays into the response level. The issue needs more votes to get attention.
