Still have it in 1.9.3-pre1 (enderman at least) (now actually tested it).
So found i the bug?? in 1.9.3-pre1?

Still an issue with 16w41a. But the bug's reproduce steps aren't right, because as soon as you switch to survival mode, you'll get detached from the mob and the filter resets to normal. For the proper steps/description, see: MC-62967

After running /kill, if you toggle perspective two times and then return to first person, the mob shader will disappear and return to normal player view without shader.
This occurs in creepers, endermen, spiders, and cave spiders.
Pressing F4 after doing this will toggle the effect

You shouldn't be able to be in Survival mode and be in a mob.
