And what happens if your application crashes before resetting the
system wide setting? What if your app forgets to reset it because
of an application bug? What happens when your users start
complaining about visual tearing in the system ?
This private setting is systemwide and affects all beam sync
operations in the system. Please do not do this. This is an abuse
of the system and it's resources. There are very likely better ways
to accomplish what you are trying than to resort to this.
Unfortunately I joined in the middle so I don't have the full
context of your problem.
I certainly don't advocate using the hack that I described. Lorenzo
asked how to disable beam sync via software, and I obliged with an
example. I wouldn't ever ship an app with sync disabled, nor one
which tweaked a system-wide property without the user's consent; it
was only for debugging purposes. ;)
What would have been much more useful for us is to have an API to
selectively enable beam syncing for various flavors of environment
and/or surface: CF, CG, NS, gl, etc.
