I don't know where to place this because I don't think it's an actual bug because it doesn't influence the gameflow in any way but I am always close to perfection so for people like me it's pretty annoying.
I found this on the chemistry building. When you attach a pipe, the already existing pipe texture is conflicting with it and it looks like it's cut off.
On this image is visible pretty clear. The left side is conflicting.
Have a nice day and happy factorio!
