Not fixed in Windows 10 either.
Chickens, Cows, Sheep, and Pigs are the victims of my device. The redstone is quick flash and fry method which works correctly in creative mode. When playing in survival mode with the same redstone setup you get a lava flash and the above mentioned mobs do not catch fire. When I force the dispensers to stay in dispense mode the lava acts as smothering block. All mobs are standing on a half slab of stone above a hopper.
The G930 headset has the same issue. Looking forward to a fix soon.
