These days I had to resolve a very annoying issue with my setup.

The problem: when I use my iPad as a second monitor, any Chrome window stops showing the video, which works perfectly on the main Mac screen. E.g., if I’m looking at a course on the main MacBook monitor, just moving this browser window to the iPad results in a blank video window. The Audio kept going, which meant that the video continued playing.

This drove me crazy.

The solution was simple (but ineffective): I had to turn off the “Use hardware acceleration when available” browser setting (located in System). Once I did that, Chrome started showing the video.

This may come in handy for you if you have the same problem, but turning off the hardware acceleration cannot be a permanent fix for this. I hope Google resolves this problem anytime soon.
