This seems to be fixed some time, as we are no longer filtering the app
events, but the window. So I'll mark it as fix released.

** Changed in: ubuntu-ui-toolkit (Ubuntu)
       Status: Confirmed => Fix Released

Title:
  topMost InverseMouseArea should removeEventFilter when disabled

Status in ubuntu-ui-toolkit package in Ubuntu:
  Fix Released

Bug description:
  An InverseMouseArea that has the topMost property as true will install
  itself as an event filter. When it's disabled, there's no use for such
  event filtering and it will therefore be just useless overhead.
  Specially when that event filter is installed on the QGuiApplication,
  which gets quite a lot of events.

  I actually don't get why to you install it on the QGuiApplication when
  your target (sensing area) is the rootItem. It would be great if there
  was a comment in the code explaining this strange decision. Maybe its
  because of the bug that you cannot filter events sent to QQuickItems
  [1] (whose fix is on the way [2]).
