The bug
The sides of flowing water/lava are moved a bit inwards (a bit like a cactus), making the edges overlap and not connect with other flowing liquid.
Note
This is not MC-1794, but instead a block model issue.

I think this is a duplicate of MC-1794
No, that one is dependent on view position, just one pixel and either white or black. This one is an error with the block model.
Affects 17w14a & 17w15a
Relates to MC-1794.
No, that's a different cause. This is about the block model. If you go near enough to this, you see a multi-pixel gap and an overlap. If you go near something that's affected by MC-1794, you will never see a gap of multiple pixels.
