app launcher icons sometimes stay 'highlighted' long after tapping them
On the 0.20.0 beta2, sometimes app launcher icons stay highlighted (or 'active') indefinitely after they are tapped. This doesn't seem to happen all the time, and I haven't recongized any reliable way to cause it, though it does seem to happen often for me. It may be hard to notice if the device's brightness is turned down, since the 'highlight' layer is very faint, but you can see it in this screenshot:
