I have noticed this behavior as well with stands on upside down slabs of all kinds. If you unload the chunk and come back, the armor stands glitch through to the blocks below the slab. Can anyone else confirm this please? I think it might be related to this bug. I was unable to track down a similar bug report.
Conor McS, can you confirm this works with the color_convolve shader in 14w21b? I have tried removing that section of the json file and I still experienced the black bar in the background. I tried modifying the json file via a resource pack and I also tried a custom jar file with the changed file. In both cases the black bar still existed.
This happens in the overworld as well.
Hello, I can confirm that this is still not fixed in 13w17a. All block updates stop after a minute or so in the End. Can any mods confirm this and reopen?

Hello there, I have been able to reproduce this on a fresh new world. This problem also occurs on my world that I've had and upgraded from 1.4 all the way through 1.13.2. Here are the steps I took.
Generated the world using 1.13.2 with a random seed, named "MC Bug" and also a bonus chest.
I placed down the available light sources one block apart.
Set the world time to 19000.
Backed up the world and loaded the copy in 19w14a.
The light sources in the world did not show any visible block light on the F3 Debug screen.
I backed up the 19w14a world again and loaded the copy.
I then placed down a snow slab in front of one block to cause the block light to update.
Please see the 3 attached worlds to see the progression of the bug. If there are any issues please let me know, thanks.
