Power Selection Glitch

Unknown

Since the latest version has hit, across both my Nexus 5 and 7, when I tap to select a power to employ it frequently selects whatever gem happens to line up behind it, instead, displaying the stats on that gem on top of the power selection window. In fact, it even lets me drag it (which I learned the hard way). I sometimes have to tap a couple of times to get it right. Looks to me as though the touch detection isn't aligned properly or is too small.
