Yes, utouch-grail/packaging contains the change in source, whereas
utouch-grail/packaging.maverick contains the change as a patch. The patch and
special packaging.maverick branch was made to avoid modifying the main package
version in the SRU. In practice, both branches contain the same change. Please
pick the one you find most suitable, and we can adjust accordingly.

Thanks,
Henrik

Bug description:
Vincent Gerris wrote on 2010-10-04 (from #637106):

What happens is, that if I touch the screen, the cursor does not move from the previous position sometimes.
For example when I touch 6 different places on the screen, the cursor would follow 3 times and the other 3 not (it would remain at the 3rd position).

Things that effect this: when I press harder on the screen, sometimes the cursor does appear on that spot.
When I touch and then drag, the cursor always follows.

This is a confirmed problem, and a patch for it is on its way.

TEST CASE: Visible on touchscreens. Move a single finger around the screen, and tap lightly with a few seconds interval. The pointer will follow sometimes, and sometimes it will not. With the patch, the pointer will follow every time.
