But its not the same issue. The black lines in PG scenery i had since FS2020 till today.
The black lines in open water bodies i did not have in FS2020, which means its a different issue.
Totally agree, the thing you reported is a new SU3 regression. This is now happening in places i have never seen it before… (joined SU3 late, and i saw this on my first flight in the beta… it is totally a new regression)
Do you have the same issue if you follow the OP’s steps to reproduce it?
• Yes, and i have never seen this before SU3. Now i get it all the time on EKBI-EKVG for example.
Provide extra information to complete the original description of the issue:
•
If relevant, provide additional screenshots/video:
• I dont have access to it rn, but i have examples of the same issue.
I think this is a new regression, even if there are similar issues out there im almost certain theres something funky going on in SU3 that causes these lines to appear a lot more frequently. In my expereince, they also show through cloud cover as kind of noisy grainy lines.
It would be nice it we could get a separate thread for this, because this way it will just get buried and will never be fixed..
OP provided screenshots from a PG scenery (Venice) but it does not mean it is limited to this type of area.
Some posts are reporting the same issue in open water zones in FS2020:
2022:
Black lines in the water - #20 by HarryFiftyOne51
Black lines in the water - #23 by nenenui
Black lines in the water - #51 by Flak99
2023
Black lines in the water - #66 by SocialPlatypus9
That’s weird. I never saw it before. I cant say i feel good seeing its still an issue since 2022 
It has been bug-logged in June 2023. The root cause is mentioned here:
Personal comments: maybe fixing it requires some deep technical changes to the way tiles are managed, what could explain the time to have a fix implemented.
They’ve been with the sim for years. Plenty of mentions from other of this.
Because you didn’t fly in areas where black lines are visible. I saw them many times when playing FS2020 but not everywhere, some areas are worse than others.
They also appear on the ground but are usually masked by trees and vegetation. You need to fly a helicopter low and slow to see them.
Since Su16 the black lines in MSFS2020-water got even worse. Much worse!
The magic of FS2020 is gone …
Yep can confirm these black lines are everywhere in SU3 2024. Didn’t realize this was a bug from way back, so looks like they are here to stay
I noticed TAA reduces them a bit (obviously will lose some framerate compared to DLSS) but the black lines are way more noticeable with DLSS than TAA for me.
So I’ve been using TAA with less frames to reduce the lines as it’s such an immersion breaker imo.

Adding some wind on the ground can help hide them as well. Especially over water.
Flying from LPPT to BIKF yesterday I noticed black lines in the water.
Also on the approach to KSFO runways 28L&R on the right side a triangle that comes and goes.
This is still very much an ongoing issue, one I didn’t find much of in 2020 but have found everywhere in 2024
Same. The lines seem either more frequent or more visible compared to 2020.
Im convinced it’s not the same as what this post is about. At least the first comments from around 2021 seems to indicate the original bug is about lines that appear in scenery around photogrammetry (which i have seen myself many times also) Now in 2024, im seeing this over every single body of water, especially when cruising. Never saw it before, only after SU3. I really hope this isnt just buried, because if this has been logged for years and it never got a fix, why should it suddenly get patched?
Here we have a user support post about the new issue in 2024… Black Lines Over Water It won’t be addressed, unless the devs actually log this separate issue..
In the meantime, im reporting this directly via zendesk
ISSUE DESCRIPTION
There are transient defects in the water north and east of the main landing runway (28R) at SFO they come and go in PC mode and I thought they were maybe a defect in background reflections. There are worse in VR mode.

On every approach.
REPRODUCTION STEPS
Just do an approach to RWY 28R SFO
