Building a mob farm on my 1.21 paper server and getting this weird bug. The clock that powers the redstone for the doors is like a totem pole and on layers that are powered by the redstone block and sticky piston have this issue. Not all trapdoors on these layers have this issue. For example on this layer the three adjacent trapdoors do not create this weird half height standing water that has the texture of source blocks. They don't act as source blocks as I cannot bucket them and when some certain blocks are drained then the effect goes away. This is very problematic for the farm however. Is this just a glitch from 1.21 being experimental or is anyone else experiencing this?
