Once we get silk working on b2g, let's align the refresh driver / compositor / input across the other platforms.

Vsync compositor on OS X passing try - https://treeherder.mozilla.org/#/jobs?repo=try&revision=561f7c233885

Try looks good on OS X + Windows with all of Silk enabled - https://treeherder.mozilla.org/#/jobs?repo=try&revision=aa339e4699fd

Is there a bug filed for graphical corruption/artifacts after enabling vsync?

(In reply to Johannes Pfrang [:johnp] from comment #4) > Is there a bug filed for graphical corruption/artifacts after enabling vsync? Not at the moment, but you can file one as a dependent of this bug. What are you seeing? You can also always disable it by setting these prefs to false on b2g: gfx.vsync.hw-vsync.enabled gfx.vsync.compositor gfx.touch.resample

Once bug 1151488 lands, silk will be on everywhere. Hardware vsync on b2g kit-kat, Windows w/ DWM, and OS X. Software vsync everywhere else. Consolidate all the preferences into one place.

I think just remove this entire comment block except for the first sentence. The rest of it may easily go out of date since people fiddling in other parts of the code may not update this. (The bits about b2g are already wrong/incomplete)
