Since moving to an M1 Mac, I’ve noticed some issues with my second screen that I do not experience with my previous Intel Mac or with my current work laptop, which is a Dell Intel PC running Windows 10. I get a lot of flickering on the screen, which is intolerable if I have Pro-motion and True Tone turned on. Note that these are options for the main display rather than the external monitor.

Hmmm it seems as though the ffi gem as installed by bundler is not compatible with a Mac that has an M1 chip. This limits my ability to preview blog posts locally. I might have to swap to a more modern static site generator (which is probably easier than working out what ffi actually does) - seems like a good February project!
