Confirmed for 1.10.2.

By the way this is DEFAULT world type. Not customized.

Affects 15w35b. Added screenshot.
Between the Plains and the EH is a completely waterless river. Great.
Increasing river depth (or decreasing max river height) could be a fix.

Affects 15w35b on Default world type.

Happens to me too.
Tested on render distance 10-11-14
Game version: 15w35b
Java: 1.6.0_65
Allocated RAM: 1GB of 2GB

You're probably wearing a helmet with a very high respiration enchant.

Things like these are for me common as well: [19:03:07] [Server thread/WARN]: Can't keep up! Did the system time change, or is the server overloaded? Running 132438ms behind, skipping 2648 tick(s)
Both with and without optifine.

BTW, which mapping utility is used to create the last image? And is it Mac-compatible 😉 ?

When creating a world with the only biome being river in customized, the land will occasionally reach y=63 (sea/river lever) or a little higher, the highest I've seen for river and frozenriver is y=66. And that's with no biome next to it... even in a frozenocean world with rivers in it a river dried up...

I created a Mushroom Island world (1.8.3) and I got many large red mushrooms and very few large brown ones.
My observation: they seem to form some kinda sub-biomes within the MushroomIsland biome: areas with brown mushrooms, areas with red ones, and areas with both.

Dupe of MC-54738 I think

Still a problem in 1.8.3

I've seen some of those half trees in 1.8.3

Confirmed for 1.8.3

Are you Dutch too...?

'Of' is not a typo, in Dutch, the word for 'or' is 'of' 😛

I've seen the same problem with spawned zombie pigmen, however that was a few months ago in 1.7 and of course I don't know anymore on which difficulty I'm playing.

Funny

You can see gravel and stone blocks, but I have to agree, it's a dark photo. Maybe edit the photo and add brightness and contrast.

No. That one is 1.7, this one is 1.8. Btw that one is resolved as duplicate.
