It seems there was a change lately regarding rendering of transparent lines (sometimes after v7.37.0).
here is a playground to test (switch between latest and v6):
It should look like this:
but now it looks like this:
There was a bug (fixed by this PR) that enabled vertex alpha for line meshes even when not requested. You can enable alpha blending by setting useVertexAlpha to true in the CreateLines options parameter (this parameter is undefined - so false - by default):
So this is a breaking change and i have to modify my code (set useVertexAlpha = true)?
Because your PR went live 2 weeks ago and the bug is still present in the playground.
That’s right. However, it was not labeled “breaking change” because it was a bug in the first place, it shouldn’t have behaved like this.
Ok. But this bug is very old. Even version 4 in the Playground has it. So there could be a lot of code which is relying on this bug. Just like my case.
I think it would be better to mark this as a breaking change.
