The dark patches are a recent bug (SU4 .11 I think). The dark lines have been around for several updates and are also a bug or, more likely, a by product of the water not being a ‘finished product’ (not 3D water)
Dark lines have been around since MSFS. This thread was started in 2021.
Ocean lines in 1.6.15 still present for me
Do we need to open a new bug report for this, or is MS looking at this thread? Just want to make sure this does not fall through the cracks…
It is already classified as “bug logged” so no further report should be necessary.
It’s been 4 years since this thread was opened. Do people believe this will ever be fixed? I don’t.
These black lines are worse and worse with each update.
OK thanks!
So I just looked through the latest Developer Blog Post, and this issue was not mentioned in the top list of bugs for MSFS 2024…
ISSUE DESCRIPTION
Description of the issue: Black lines/artifacts on water, seems like the dge of water tiles

Since this topic was initially created back in Aug ‘21, more then 3 years prior to the release of FS2024, it is not fully understood that this bug is also present in FS2024. Perhaps adding that fact to the topic would alleviate that confusion.
Also, after doing a quick check of the bugs report from Oct 9, I do not see this issue listed anywhere. Perhaps it was previously listed for FS2020 and has since been resolved and removed, but it is still present in 2024
Thanks
It was never resolved in FS2020 and was carried over to FS2024, like many other bugs. The earth model is made of tiles stitched together. These black lines are also present on the ground but they are usually masked by grass and trees. I reported it 2 years ago and the answer was “Unfortunately, issues like this have to be fixed by hand.” So considering these black lines are all over the world, this bug will never be fixed.
Still have black tile lines when flying over water in SU3 PC. Been an issue since SU2 for me.
It needs to be re evaluated for sure. It is a massive eye sore and takes me out of the sim. I see it on every single flight. Something happened during SU3 for 2024, and made it appear literally everywhere and its shocking how it is getting no attention from Asobo.
I don’t think photogrammetry has anything to do with these black lines. I see them in the middle of the ocean, around French Polynesia. Far away from any photogrammetry sceneries.
Good to know that. I just hope we get some resolvement for this!
While I don’t see dark cutouts on .19 I notice dark lines from an altitude >10000ft at individual water tile edges while flying over the ocean. These lines render also through clouds:
These lines were also visible on .18
As it might not be visible across all players here are some relevant information:
- RTX 4070ti Super (most recent game ready drivers)
- 21:9 at 3440x1440
- DLSS version upgraded to the most recent one using the Nvidia App
- TAA in use in combination with Frame Generation (x2)
So when I encounter this bug, I typically see what look like “seams” or “edges” between ground tiles. I’m pretty much guaranteed to encounter them over any body of water and at any flight level. They’re generally rectangular in shape.
