The open source Radeon driver also does a good job of avoiding tearing.  I think there are some pathological cases where it can still occur, but it is pretty rare.  Catalyst was terrible at avoiding tearing the last time I used it (getting on to be 3 years ago now).  I haven&#x27;t looked into it, but it is possible that the tearing issue may not be solvable without a KMS driver (i.e. no binary blob drivers can do it).<p>I used Wayland&#x2F;Weston for a full work day about a year ago to try it out.  It <i>really</i> was very nearly ready.  I can&#x27;t quite remember what problems I ran into, but I could do my work (as a web developer) with very few real problems.  Probably it&#x27;s time to look at it again.
