LOD flicker on water chunks with DH 2.3.x + shaders

UPDATE: I can isoalte the OpenGL rendering error spam to occur only with DH 2.3 (no other mods installed, vanilla mc), logs: https://mclo.gs/FCHDhRd
I have been using the nightly DH over the past few days and there is a persistent flicker on water chunks when they are being rendered as LODs and shaders are enabled. I tested with a clean instance earlier today (modlist attached)
Recording of the issue: https://www.youtube.com/watch?v=66bxWZieEU8
Logfile dump of the run in this specific video: https://mclo.gs/eN9hHU4
System specs: 7950x3d + 4090.

It is persistent across all shaders I have tried, the video specifically shows it with two of them. The issue is not present in DH 2.2.x with or without shaders, it is also not present in DH 2.3.x when shaders are disabled.
I have tried several combos of different mod versions of Iris/Sodium/Embeddium but nothing so far has made it go away.

The logfile is full of the following message being spammed 100+ times a second (regardless of shaders being on or off):
[Render thread/INFO]: OpenGL debug message: id=1282, source=API, type=ERROR, severity=HIGH, message='GL_INVALID_OPERATION error generated. Texture name does not refer to a texture object generated by OpenGL.'

This is all a follow up from: LOD flicker in water that might provide more context and another person with a similar issue as mine.
