Insane level of world space reflection culling

[creammybum]

as you can see some of the trees on the edge of the far away reflection are not visible, the only difference between the pictures is the camera is moved a few pixels. im pretty sure the whole point of world space reflections is for this not to happen so i hope you can fix it.

Do you have any mods that modify the games culling optimizations? Because this is a bit too extreme of an example and it doesn't happen on my end. I only see stuff like these when looking at reflections of gigantic structures that are many hundreds of blocks tall. Disabling this optimization completely would increase the performance cost of world space reflections by multiple times to the point where it probably wouldn't be worth enabling for most people anymore.

Looks like this happens at specific times of day. It's not something I can fix directly without reducing the performance by something like 30% though. Best we can hope is for Iris to fix it I guess, but it's not really a "bug" from the Iris' point of view.
