when ever i use any kind of shaders i have the problem of the colors not being shown correctly they either get dulled somewhat or are displayed as black as seen in the screenshot.
furthermore when looking at around sometimes it just disappears completly or shows the colors correctly for a brief time
any ideas on how to fix it?

It's likely the mods conflicting on the render tick. I can look into it and see if there is a fairley simple way to fix it. I'll do some testing but I can't promise anything...
