I have Installed the mod and it seems to work ingame. I can add blocks and everything but when I enable Xray no blocks are shown

Shaders Maybe?

I'm also having the same issues, but I have no shaders. I do not have Optifine installed.

Don't use shaders, problem solved. Out of curiosity, what is providing shaders?

I use Complementary Shaders on Minecraft 1.19.2 vers and Xray stopped working, although everything was working fine before (with shaders). It just stopped working for no reason (I only can add blocks but when i turn on Xray nothing happened.

Having the exact same issue. It was working just fine but then just randomly stopped working.
