Fences seem a bit glitchy when held.

I play Pocket Edition on a tablet, a Hipstreets Flare 3, which uses Android but wasn't listed.

Today I noticed something while building. When holding a fence, the ends of the fence are bugged. They have either no texture and are completely white, or have red and green pixels instead of fence texture like it usually does. I only noticed this today, and I haven't found anyone complaining about it, so I think it's either a random bug or it happened due to an update. It's only a minor bug, nothing too big, but a bug non the less. If possible, please fix 🙂
