[Affected versions]: - Firefox Nightly 52.0a1 [Affected platforms]: - Windows 10 x64 [Steps to reproduce]: Make sure that the build has e10s enabled. If not, go to about:config and right-click -> new -> boolean to add the pref "browser.tabs.remote.force-enable" and set it to "true". 1. Go to about:config and set the "dom.w3c_pointer_events.enabled" preff to "true" 2. Go to https://patrickhlauke.github.io/touch/tracker/multi-touch-tracker-pointer-hud.html. 3. First use one finger to drag across the canvas and then try with more. [Expected result]: - The tracker should run smoothly. [Actual result]: - The tracker experiences lag when Pointer Events is preffed on. [Regression range]: - This is not a regression since this feature is new. [Additional notes]: - This only happens when the pref "dom.w3c_pointer_events.enabled" is set to "true". The tracker does not lag if the preff is set to "false"
