MC 1.20.1 I can't have Distant Horizons and shaders on together.

I looked through the faqs and unless I've misunderstood and this is possible a Oculus issue(?) I'm not sure what is causing this. I have Ereddium, Oculus, and Distant Horizons installed. I'm using Bliss, which is supposed to be compatible. But I can only have one working at a time. I'm not sure what is causing it and I'm sorry if I'm asking something obvious. I did search on google and also here in the discord but I couldn't find a fix. This is on single and multiplayer btw. I am exploring the chunks on MP of course (you can see it one of the images).
