Despite searching for maybe 10 minutes, I couldn’t find a prior report on this issue despite definitely seeing one beforehand.
When turning on this debug renderer in F3+6 and travelling past a power of two boundary, the geometry rendered will become more stretched or flattened. The attached screenshot shows the appearance at 16777216 blocks.
There is a float being used somewhere where a double is expected, resulting in these geometrical distortions.

I’m assuming you couldn’t find it because apparently the word “heightmap” was not present anywhere in the report, which tripped me up as well when searching just now. I’ve fixed that now.
