Since Sunday (April 1st), red and blue are sometimes swapped when I watch videos on YouTube.
Here is a screenshot of the RvB episode at 1:28.
Vimeo is OK, other web video services are OK, only most YouTube videos are affected ... well, all that I could find so far.
This video looks OK in Firefox but it's broken in Chrome. The episode of RvB looks wrong in both browsers. Local videos look file.
What could be causing this?
