Confirmed in pre8 , problem also for other mobs such as skeletons , zombie pigmen , wither skeleton , creepers...

Confirmed as well. I had a mob farm working fine in pre7, but pre8 broke it due to this problem.

Confirmed as well, Iron Golem in iron farms will not flow through properly. Works perfectly in pre7, breaks in pre8.

Ditto. zombie, skele, iron golem mobs slow or stop on 7th or 8th block from water source. Not an issue in pre7.

Confirmed in 1.13-pre9

Gnembon discusses details with the flow of water bug, adding detail that mobs SLOW DOWN in the lower volumes of water, after 5 blocks of flow, so that detail should be considered a part of this bug report. He also shows a few workaround solutions for this problem. I also agree with Gnembon that days before the planned release is a very poor way of introducing this behavior if it is "intended". This behavior also affects players using water streams, including "slowing down" after 5 blocks of flow.

Actually, this bug and MC-133421 appear to be the same bug in two different reports. Can we call this one a dupe?

This behavior appears to have been reintroduced with at least Snapshot 18w44a. I still get pushed out of the water, eventually, but it looks like it's back otherwise. 😞
