@minimapletinytools as I mentioned in my email, the current implementation of inputInFocusedRegion seems to drop a lot of events. Especially noticeable when you try to use the scrollwheel for some reason.

But to recover the existing behavior (at least until we figure out a better approach) have a look at the changelog.

myTile :: (MonadFix m, MonadHold t m, HasInput t m, HasFocus t m, HasLayout t m, HasImageWriter t m, HasDisplayRegion t m, HasFocusReader t m)
  => Dynamic t Constraint
  -> m a
  -> m a
myTile c = fmap snd . mkTile (mkPane inputStartedInFocusedRegion)
