A frequent occurence against water backgrounds. It was there in my FSX and P3D as I recall. It is a AA/transparency thing I think. It is the type of flaw that an old timer like me has learned to ignore but it is weird to find it yet again in the « new gen » sim... like morphing 😏.

OK, if you don't resolve it with gamma correction off please let me know the location and weather/time conditions to test in order to reproduce it.

Sure, but basically the topic starter image shows exactly this: a water surface that would show bright reflection of the sky and some trees directly in front of it. THEN the tree textures get this annyoing "halo" around it. Will check the AA gamma correction as soon as I find time to fire up my sim rig.

Ok, @MrFuzzy and everybody else interested to see if they can recreate the issue: I chose something by chance, Gillies Bay in Canada, CYGB (today, preset few clouds, local time 11:30). Takeoff south, just short above the trees, look into the direction of the small Cranby Lake left of the runway. As soon as the reflection of the water and the tree lines are as on the screenshots, you will see the glowing edge, I bet quiet some money on it. As a matter of fact, this small test cleared something for me: the issue appears only if there is a bright reflection on the lake but the terrain reflection is darker. Trees that then should basically be in front of a bright reflection darkened by the dark terrain reflection get the glowing edge. That is why you wont see it in every scenario...

Above screenshot was taken with AA gamma correction on, sadly turning this off via nVIDIA Control Panel changes nothing:

OK, I can see it. It happens where the contour of the trees overlaps with shadows, in this case the shadows of the trees on the other shore.

It may depend on how the trees are generated, they are not exactly 3D elements with definite edges... you realize it when you pass through them with the drone. I don't even know if DX12/DXR could correct this...

Exactly, it is somehow related to the fact that the tree outlines (e.g. the leaves or needles) are no 3D objects but only textures. For 3D structures, the issue does not exist (buildings or planes).

More worrying is that it has made the fuselage of your plane disappear! 

Thanks for this.  I will look at this scenario tonight in case I have a setting that causes it to not appear.  My guess is that I just haven't noticed it properly before.

The one that gets me is the way reflections on the water disappear when they are close to the the frame of the plane windscreen, especially when banking.
A good while ago, somebody said that it is just due to how screen space reflections show.  I wonder if it might be linked.

Yes, this also bothers me all the time, add the totally bugged reflections of bridges and ships and you can basically conclude that this water reflection part of the engine is total cr* and by far not on par with other aspects of the graphics engine. 

To me it looks like an issue with the screen-space reflections. It seems that the reflections are just getting occluded around the trees, rather than exhibiting glowing lines. Perhaps they cannot be drawn behind alpha textures.

I wouldn't count on DirectX 12 fixing this, except maybe for ray-tracing.

This problem is well known to 3rd party developers for P3D and MSFS, see https://www.fsdeveloper.com/forum/threads/strange-lights-effect-under-roof.452084/ . It appears to be a bug in the graphics engine of the simulator.

Just an idle thought... Would turning off (or on?) "Ambient Occlusion" make any difference?

It does not, already tested it

No, it shouldn't, because ambient occlusion is a technique for generating soft shadows around 3D objects.

It looks like it could be an antialiasing issue. Try flying the scenario with AA turned off, and cycle through the other AA types to see if there's a variation to its appearance. I suspect the glow may disappear with AA off, so I'm interested to see.

I also see this glow issue.
As well as color banding in clear skies or water. 
And the reflections seem to taper off towards the right or left in the image. 

I didn't really notice it until SU5. But it might have been there earlier.

Yes, color banding came with SU5 also according to the official forum reports. I realized recently that it does not occur in HDR10 so I play in HDR now, but not many people have HDR monitors... definitely something to be fixed.

But reflections and shadows disappearance at the edges of the image is expected for the raster technique. We could get rid of this only with ray tracing.

That's interesting! Yep I don't have an HDR monitor, so I can't use that option. I think the sim felt a bit more washed out after SU5, and the color banding is actually takes away from the immersion.
