What happened?

By default, the RYD ratio bar is supposed to show likes in white and dislikes in grey. This worked fine in the past.

But now, the bar is entirely grey:

However, if I enable “Colorize ratio bar” in the RYD settings, the colored ratio appears correctly (for all three color themes):

This occurs for me on all videos, in both Firefox (with both my default profile and a blank test profile with no other add-ons or customizations) and Chrome.

Note: The RYD userscript version has the same issue.

How to reproduce/recreate?

Load any YouTube video with a visible likes/dislikes ratio (may be less obvious if a video is 100% liked/disliked).

Will you be available for follow-up questions to help developers diagnose & fix the issue?
