I don't know know if this is a shader or DH problem, but some of the shaders I have tried (the one in the screenshot is Nostalgia VX) cause this weird rendering issue where there are boxes around nearby objects, and they disappear as you move closer. My primary shader is Photon, and it does not have this problem.
If this is a DH problem, is there a setting I can change to fix this? The version I have installed is 2.3.0 -b, and I'm playing on the server.
