Hello again, I was testing the latest version (ver. 9.1e) of this shader with the pale garden in 1.21.4 and the Twilight Forest mod in 1.21.1 and noticed a major issue: when transitioning between the pale garden and a biome with a normal sky color or between certain Twilight Forest biomes, there's a major cutoff as illustrated here:

This happened with ver. 9.1c as well. It would be really nice if this was fixed!

GPU: Intel Iris Xe Graphics
RAM: 8GB
CPU: i5-1135G7
OS: Linux Mint Cinnamon 22.1

The issue should be fixed in version 9.3.
