smoothing drawing lines (antialias webGl?)

[PetukhovArt]

Hello !
I use scene-mode 3 and the height of each my geometry is 0 now ( i create / change height by default)
I change polyline settings with custom color and
Polylines on the globe look not smooth.
Any solution to change this ?
I tried antialias setting , but it's not working.

const webGlContext: VcContextOptions = { webgl: { antialias: true, depth: true, stencil: true, powerPreference: 'high-performance', preserveDrawingBuffer: false, }, allowTextureFilterAnisotropic: false, };
