in 3.3.1 the end of the line flickers like crazy
compare 3.2.0 https://codesandbox.io/p/sandbox/snowy-cdn-74l2v3
to 3.3.1 https://codesandbox.io/p/sandbox/zealous-chebyshev-8hj3fv
it appears that 3.3.0 is fine too
With 3.2.0 version, the end of the line doesn't flicker definitely, but the beginning of the line flickers... You didn't notice it because the beginning of the line was out of the screen. https://codesandbox.io/p/sandbox/pensive-minsky-6qwc9j?file=/App.js
With 3.3.1 version, the beginning doesn't flicker any more, but, as you said, the end flickers...
Strange 😂
This issue is caused by the changes done to fix #19.
Speciffically it's the use of this.copyV3 in the else clauses that causes the flickering.
Reverting the two else-clauses in MeshLineGeometry.ts seems to remove the flickering (but of course cause regress #19).
