If you place a line of redstone wire that stretches for a sufficient distance, and then stare down its length, it will appear to expand to the thickness of a full block in the distance, and also appear discontinuous at parts.
There could be changes made to the textures' mipmap settings that would resolve this, but Iām not familiar enough with how to do this.
Thank you for your report!
After consideration, the issue is being closed as Won't Fix.
Please note that this is not the same as Working as Intended, as this bug report correctly describes behavior in the game that might not be the intended or desirable behavior, but it will not be fixed right now. Sometimes, this is because the issue reported is minor and/or impossible to change without large architectural changes to the code base.
