I assume there's a reason Intel didn't make that particular setting the default in their x11 drivers. While it certainly fixed the screen tearing issue, I presume there was some tradeoff which made some other feature worse off. Wayland however I assume is already built so it doesn't need the driver to implement some workaround to fix it, it's already designed to correctly handle video output by ensuring only the full frame is rendered every single frame.

I think the extra requirements aren't a problem on modern cards. However on lower end devices e.g. the older intel iGPUs, I could see this becoming an issue.

My money is on Wayland enabling the equivalent of this setting by default.

Did you notice any problems after enabling the setting? If you didn't notice any problems, then why would you care about any hypothetical tradeoffs?
