If you look at certain angles in the debug mode world while in the nether, either everything or everything but the chunk you're in will disappear.

There is. You can set your game mode to creative once inside the debug world, and then go through the nether portal block, and yes they do randomly disappear.
I understand your skepticism, but I just went to play around with game modes, going through the end portal etc (end portal gives credits and a teleport back)
And eventually I met the nether portal, which takes you to the place in the screenshot.
So yes, the bug is real, but isn't it a bug that you can go to the nether in there, or that you can switch game modes, rather than this visual glitchiness?
Edit: This is in the 1.8 release.
You are not supposed to enter the debug world in any game mode except spectator mode.
The only bug is that gamemodes are not locked to spectator mode, see MC-60033
There is no nether debug world.
