If your here for a separate issue recently with coloured lines appearing in the middle of the screen on images and in videos, its literally as simple as disabling RGX which enhances video and images.
Here's how to deactivate it:
In the top right next to the user icon is the settings icon, click on it and scroll down until you see RGX and click on both options so they are off.
Its an experimental feature so its not that surprising to see a bug.
