[Matthew Paul Thomas <mpt@xxxxxxxxxxxxx>]

This is a toolkit problem, not just a System Settings problem. The same
problem happens, for example, with apps in the Apps scope, and events in
the Calendar's "Agenda" view. It is not noticeable in other places (for
example, Gallery, Contacts, and Tasks) because their list items don't
have touch feedback at all yet.

The problem is this: If you touch any control, the toolkit immediately
treats it as a touch of the control itself. If you immediately swipe,
the touch is cancelled, but by then the control has already changed
appearance. So you see a brief and unattractive flash of the pressed
state.

In iOS and Windows Phone (in my testing), if you swipe within a certain
period of touching, about 200ms, you are probably trying to scroll or do
some other swipe gesture, so any control that you touched does not act
as if it was touched (probably because the toolkit doesn't even pass
through the event). The control only acts as if it was touched if you
touch it for at least that long. The Ubuntu toolkit should do the same.

Title:
  Touched control has pressed appearance even when you swipe quickly

Status in ubuntu-ui-toolkit package in Ubuntu:
  Confirmed

Bug description:
  Using rtm-17, recently an effect got added to indicate that a panel is
  selected. The selection color is displayed on click though, which
  means you get it drawned when scrolling on the grid, which feels wrong
