Yes, I only see the blinking when using Chests Anywhere. I tested vanilla, then with SMAPI and no mods, and then with all my other mods but not CA, and then with just CA installed. Blinking only happens with CA. Edit: I've taken a closer look (better late than never) and it seems the blinking is only happening on the trash can, name of chest, and chest location, not the entire menu screen. The trash can is really noticeable, it blinks when removing an item from a chest or placing into a chest.
