Scrolling with a touch screen (Sony VAIO Pro 13, Firefox Nightly on Windows 8.1 x64) doesn't work - page stops scrolling after a "flick" gesture after touch is lifted (instead of slowly fading to a stop as earlier). Kinetic scrolling worked before, latest update auto-enabled e10s on Nightly - kinetic scroll works still on Dev edition, and disabling it & restarting Firefox results in this bug disappearing.
This is widget/win32 plus gfx/apzc related. Not e10s specific.

:flaki, do you have the layers.async-pan-zoom.enabled pref set to true?

As much as I'd love to help, my touchscreen has just kissed goodbye, so until I can return my PC to RMA, I can't test the touch functionality. In the meantime if anyone with a Win 8.1 touch machine (Surface, or Touch-enabled ultrabooks/hybrids) could jump in & see if they can reproduce that would be sweet. :|

You don't actually need to have the touchscreen working to check if the pref is set to true. Just go to about:config and type the pref into the search box.
Whoah, yes indeed. But it's unmodified, layers.async-pan-zoom.enabled is set to the default "false".
Thanks. If APZ is disabled then this is likely a win32 widget/e10s issue? I'm not sure. Moving components, but I can dig out my Surface and kick off a build to see what's going on.

We will not work on this, apzc + touch support in win32 widget solve it.

For reference, if you want to enable APZ + touch support, do the following on a recent nightly: - Enable e10s - Set the layers.async-pan-zoom.enabled pref to true - Set the dom.w3c_touch_events.enabled pref to 1 As per the last time I tried this, it should get you back to the behaviour you were seeing originally where touch scrolling has "kinetic" behaviour. You may run into other bugs with this configuration though.
