Come to think of it, one probably could modify some combination totem/cogl/clutter to avoid tearing in old-style non-compositing window managers. But that's unlikely to ever get done considering Ubuntu has been defaulting to compositing window managers for some years now (Unity/Compiz, Gnome Shell).

With default X settings, I get tearing across the top of the screen (but I also get very noticeable tearing in other applications); if I enable TearFree (which eliminates tearing in Chrome), the tearing turns into jagged black flickers which extend from the top of the screen right down to near the bottom of the screen on some frames. The flickers are visible in screenshots, so I have attached one.
