I could not reproduce this bug with the first command (setting the painting to invulnerable).
With the second command (changing the motive of the painting) the bug was reproducable BUT ONLY when the size of the original motive and the new target motive are different! For example in the screenshot above the Motive 'SkullAndRoses' can be seen, wich is a 2x2 block motive. When you try to set the Motive to 'Kebab' - wich is a 1x1 block motive - using the given command, the painting will turn invisible. A relog / re-entering the chunks will update the painting, turn it visible again and display the Motive specified in the command. The size of the painting will be adjusted accordingly.
If both original and target motive size are identical, the painting will not turn invisible. After setting a new motive it will, however, still display the original motive until the player relogs / re-enters the chunks.
==> The painting doesn't ever truly get turned invisible. Clients, however, are not immediately able to see changes made to a painting's entitydata (in regards to its motive, primarily) using commands, and the client will fail to render the painting completely, if the size of painting changes abruptly due to a new motive - until the client relogs / re-enters the chunks.
I hope this clarifies what the issue actually is.
All tests were done using MC version 'release 1.8.7'
