Jagged edges in reflection

Hey guys, I met a problem recently and looking for help.
Can you see the jagged edges on the car window, I don’t know how to get rid of them.
There is only a HDRI backdrop in the scene with a basic material of window. Object mesh has been set to high precision tangent basis.
Also you can see my HDRI texture settings below.
When I get close enough to the window, the error disappear, but when it comes to distance, it’s pretty obvious.
Hope someone can help, thanks,

Got the exact same issue, using a CAD model of a car and all windows have the same artifact. Hopefully going to be able to figure it out so if I do I’ll make sure to come back and post the fix.

EDIT: turns out my issue was with the high precision tangent basis setting in the mesh editor. I needed to actually hit apply changes lol. Still relatively new to UE.
