Minecraft: 1.19.2
Forge: 43.2.4
Snow Real Magic: 6.4.4
Rubidium: 0.6.2a

I really love the Snow Real Magic mod but it breaks a bit with Rubidium by causing a lot of z-fighting with the snow layers on stairs, slabs, and full blocks while also causing snowed plants to become invisible, which can be used for cheating on servers for example:

The z-fighting and invisible blocks only happens when the mod is with Rubidium so I ain't sure what's going on completely... Also to note that the z-fighting only happens on two sides of the blocks on average and doesn't happen at all on snowed fences and gates.

Should be fixed on their side
