Comment 105 for bug 1305522

@Javier Vela
Did you try 3.17-rc1? If so, take a look at this: https://bugzilla.kernel.org/show_bug.cgi?id=82601

@piotr
If the jumps happen when you use two fingers, maybe this (http://lists.freedesktop.org/archives/xorg-devel/2014-June/042790.html) could help. If this is the case, then it's not a kernel bug.
That patch could also help if the bug you are experiencing is the same as the one you linked which seems to be a kernel bug.

Note that the patch I linked is not a kernel patch, so it's not something that can be included in the backported kernel.
