OK. When I enlarge it, I can now see.
I wouldn't call it a major problem though. Just a niggle.

I downloaded and installed the National repaint (screenshots).
I am not a painter but it looked ok to me (P3Dv4.5).

Why does China Leaf use AVSIM Library instead of PMDG's official certified repaint lineup in PMDG OPS Center?

Another one. Seems the plane isnt affected at all. One can see change when looking at the thin yellow line on runway, below right wing, between plane body and 2-nd engine. With SSAA this line looks a bit smoother. But the whole plane is untouched, same pixels.

And one with a non PBR model, the CS 757. Clearly visible how AA affects the plane.

Its very interesting.... Now i restarted the sim on 8ssaa set and all is good. BUT again setting changes dont have any affect. I can set it to 2 MSAA and it still looks exactly same as with 8 SSAA

It's called "specular aliasing", can google for more details.

It's hard to show in screenshots, much more apparent in motion.

There are ways to solve it with no performance impact, but it's up to LM to include the fix.

Do you reboot your PC between graphics changes?

I never mess with the MSaa/ssaa etc.
Whatever the default is ... is what I leave it at.

I seldom go outside to look at the aircraft [ I am not a livery painter ] except during testing.

Non PBR liveries need no reboot, as you can see in the CS757 screenshots. AA changes will reflect after clicking OK button. Its the PBR liveries that dont show effect
