Watching any video in Chrome has red boxes FIXED:
Version 53.0.2785.89 (64-bit) fixed it

OLD:
I've been noticing this for the last couple months, but whenever I watch a video in chrome (Version 52.0.2743.116 (64-bit)) I see small red boxes over the video. The boxes jump around and flicker. It doesn't matter which site it is for (screenshot is youtube and steam)

Things I've tried:


It does not happen in safari 
chrome://flags/#disable-accelerated-video-decode (disabled)
chrome://flags/#disable-cast-streaming-hw-encoding (disabled) 
chrome://flags/#enable-webrtc-h264-with-openh264-ffmpeg (disabled)
