Issue also on AMD Ryz5 with RTX3060, drop in FPS of about 15 to 20%
with huge spikes in FPS-decrease when entities appear in POV

Behaviour also present with a repeater-clock (chained 3-tick repeaters). Loading of old world => Repeater somewhere in the middle was active but not pushing forward the signal.

I guess this issue can be closed.

After the released 1.18 seed-info on chunkbase, i do see the "new" map-content.

The 1.18-seed map does show a humongous "cold" region at the same location for the 1.14-seed.

So i guess the resolution is "expected behavior as implemented"

However the transition on water between chunks could be a little less straight edgy. (see previous images)

Images comparison seed loaded in 1.14 vs 1.18

same issue here. W11. (Insider build, 22000.282)
