Link XBox 360 was fine. Wii U was... less awesome, but not truly bad. XBox One was fine for a while until more recent updates. PS3 was fine. All consoles older than XB360/PS3 were fine (includes original Wii).

So Microsoft did an update, and now my XBox One (original version, rather old) is actively flickering. Like, it's visible even to people without crazy bad eyes. It might be time to update to an XBox One S... yet another expense I wasn't anticipating this summer. 🙁
