Bug Description

MX4 running 451

After some period of use, the switched frequently becomes unresponsive, either it does not reveal right away on a right edge gesture, or when revealed selecting an app does nothing for some seconds. When in this state it is inconsistent, will work a few times, then not work.

This regressed with the new implementation.

It does seem to require that the browser or a webapp is open. I cannot reproduce it otherwise.

On M10 tablet I notice some lag after swiping an app from the spread. Sometimes it takes about 2 seconds to 'align' the rest of the apps in the spread after an app was swiped away.

^ comment #4 sounds consistent with the animation problem we had (have?) with right edge switching. The alignment/settling at the end of an animation would take a second or two, during which input would be ignored. Perhaps trying to complete the current animation after the user has already requested some action is the problem.
