Comment (by suv-sf@…):

 Replying to [comment:5 suv-sf@…]:
 > [*] Oddly (at least unexpectedly to me), the cursors seem to work even
 better with the Quartz backend compared to the X11-backend which supports
 fewer than the Quartz backend (in gtk3-demo), and only if patched with the
 latest commits from the git branch (committed right after the 3.18.5 tag).

 Clarification: this was tested (with either backend) on a MBP 13-inch,
 Late 2011 with just the built-in trackpad and no external mouse attached -
 gtk3 3.18.5 as is apparently fails to properly detect an input source
 (core pointer) on such a system.
