On the other hand, I found places where vanilla MC 1.11 renders the landscape correctly, but OptiFine instead ignores a chunk (or even several) while rendering, depending on the camera position and viewing angle. If interested, I have a saved world available.
__
P.S.: Discussed this issue briefly in the OptiFine bug tracker, where sp614x provided an additional test world with a very obvious case, where both vanilla MC and OptiFine consider chunks accidently as not visible (don't move, just turn).
MediaFire shared folder with 7-zip packed world "InvisibleChunk" and a preview how it looks for me right after loading this world. In addition, "FlatCreative" world from the OptiFine tracker.
Attachment: MineCraft 1.11 world "saves/FlatRed", packed with 7-zip 16.03, demonstrating long distance teleports onto different grounds, some with reduced heights.
Yes, it happens for me with v1.11 too.
I will try to create a new flat Redstone world to demonstrate and upload it...

P.S.:
It is necessary to travel a large distance so that the game needs to load a large amount of the world. The bug does not happen when you teleport "in sight".
It also happens when teleporting onto "farmland" (with growing crops), because it is missing the same 16th of height like "grass_path".

IMHO not a duplicate of "half of the door invisible but still blocking when closed". The door is completely gone.
I placed the door in a 2x1 hole surrounded by granite blocks, with normal stone below. Exit and save (maybe quit and restart the game), reload the world: Doorframe is empty. Wooden door disappeared completely.
Not only the menu, also the game progress messages in the console, etc.
@ Tiya tehJak:
No, this is a different issue. If you can approach them and fall through the world, they were not loaded. But this report is about chunks which are only considered not visible although they should be, and they are loaded, as they are visible from a location or just in a different angle, and usually at least one chunk away from the camera.
