In 16w03a only EnderCrystals seem to be affected (MC-111339)
/setblock ~ ~1 ~ minecraft:mob_spawner 0 replace {SpawnData:{id:"EnderCrystal"},Delay:32767s}mob_spawner with a high delay tag cause the Entity inside to "stutter".
Example command
/setblock ~ ~1 ~ mob_spawner 0 replace {SpawnData:{id:Sheep,Color:1},Delay:32767,MinSpawnDelay:32767,MaxSpawnDelay:32767,SpawnCount:1,SpawnRange:1}
This seems not to effect all Entities inside the spawner, FallingSand or ArmorStands for example seem to be uneffected.

Not seeing any stuttering, can you record a video?

That is strange, it happened just one hour ago and now I cannot reproduce it anymore.

Cannot reproduce in 16w43a.
Is this still an issue in the most recent versions (currently that is 1.10.2, or 16w43a) of Minecraft? If so, please update the affected versions and help us keeping this ticket updated from time to time. If you are the owner/reporter of this ticket, you can modify the affected version(s) yourself.

Confirmed that ender crystals stutter in 1.11, but they stutter regardless of Delay. Creating a separate issue...

For shulkers as well as soon as you provide on additional NBT tag (tag does not have to be valid):
/give @p mob_spawner 1 0 {BlockEntityTag:{SpawnPotentials:[{Entity:{id:"minecraft:shulker",CustomNbtTag:0},Weight:1}],Delay:-1s}}Edit: This is MC-111381

Please close this report but leave the fix version as it is.
Appears to have been fixed somewhere between 15w44b and 15w34d.
