Logarithmic Depth Artifacts
See original GitHub issueDescription of the problem
Logarithmic depth appears to be broken in three@0.109.0. Possibly related: #17442.
On my system, I see lots of depth artifacts in setups that use logarithmicDepthBuffer. I don’t know if this problem is hardware-related; would be cool if someone could verify!

I get the same artifacts in one of my projects where I use logarithmic depth for testing purposes:

Oops I misunderstood “test 1” to be the first test I posted originally… I just changed #17631 to use the
vIsPerspective == 0.0comparison.If the depth buffer has minimal precision, I guess rounding a second time could be a problem… Given that, ‘test 1’ would be my preference.
vIsPerspectivecan be greater or less than zero due to roundoff.Zero times anything is zero. I think it would be perfectly safe.
