X server (due to whatever reasons, like maybe a binary-only video driver
for a legacy video card), this patch may work for you.
It's a first attempt at backporting Peter Hutterer's touch-grab-race-
condition-56578-v3 branch.
Upstream marked this as fixed. So this should be fixed in saucy now.
Backporting this is non-trivial, and it might be easier to test if using
a newer version of onboard fixes this problem. Newer versions of onboard
workaround it by using xi2 events directly.
