Reproduce: run exp/shiny/example/tile using gldriver on OS X, drag the image around with mouse.
Expected outcome: The tiles smoothly move around the window.
Actual outcome: The animation is smooth, but there is a delay (up to several seconds) before they begin moving.

This is on OS X 10.10, on a MacBook Pro (Retina, 13-inch, Early 2015).

I had the same issue with a proof-of-concept game engine I'm working on. On linux and android, it works fine, but on mac input is delayed several seconds (in addition to the keyboard on working)

@boomshroom are you using x/mobile/app or shiny on OS X? I believe I have this issue under control in the app package but I have not ported the fix to shiny yet.

@crawshaw shiny. mobile/app works fine on both linux and mac. (I have a shiny backend and an mobile/app backend with most code being shared between the 2)

Ok great, then when I finish up porting my changes next week this will be fixed.

This has been fixed.

There still is some input lag (unlike linux where it's practically instant), but it's much better. maybe a half-second of input lag.
