For a month or two, I've had this consistent issue when playing videos of all kinds, where the screen color shifts slightly when on-screen-display elements like volume and playback controls appear and disappear.

This includes the system volume adjustment icon, the YouTube video playback controls, and QuickTime playback controls. It's strange because you'd think YouTube's on-screen controls have nothing to do with QuickTime's controls, yet it seems there's something going on at the system level related to video playback.

When playing QuickTime or YouTube videos, the color of the video is slightly different when the controls are visible than when they disappear.

When playing a YouTube video, the screen will go completely black for a split second when the macOS system volume adjustment icon appears (the grey square in the middle of the screen).

This is super annoying as I work in video color grading. This is a recent issue and only started happening a few months ago at most.

It only happens in full screen. Videos playing in windows are not affected.

Anyone else with the issue?


See images below. There's a color shift when the OSD volume control comes up. It's hard to notice the shift when the images are side by side, but when they come after each other, it's obvious.
