On iOS, we are using a timer that’s sync’d with the screen refresh rate. This was addressed back in 2010.
On the Mac, there are still issues for multiple reasons: (1) we have not switched over to a timer that’s sync’d with the refresh rate of the monitor and (2) When we added support for native widgets (textfields, webviews, etc), this may have gotten worse due to some under the hood changes to support overlaying native widgets on top of OpenGL. We’ve filed numerous Apple bugs to address this, and are investigating workarounds.
On Android, there is actually no timer at all. And hence, no semblance of support for sync’ing with the refresh rate of the device’s screen. Which devices are you seeing this on?
