I don't remember if I mentioned this before but I "solved" this annoying problem last year because this issue was not getting fixed. I installed Linux Mint 17.3 Cinnamon. The shade works fine and the added bonus was Mint doesn't use UNITY. Back to a comprehensive desktop. Mint is based on Ubuntu so the transition was quite painless.
