I've had an ATV 3 for years and now have an ATV4 but they both share a common problem. Sometimes I notice that the bottom left corner of whatever is on the screen is about 1/2 second behind in being updated. It's a rectangular size area maybe 1/12 the size of the entire screen. A reboot of the ATV3 solved this problem for weeks until it would show up again. On the ATV4, a reboot solves the problem for a day, then it returns. This happens on the menu or inside Netflix, so it must be a system-wide problem. Anyone else seeing this or have I just been fortunate enough to have two ATVs with this same problem?
