I landed the patches of bug 953146. Perhaps, it fixes this bug. Would you test this with Nightly? Perhaps, today's or tomorrow's Nightly will have the patches.

Tested with nightly 29.0a1, synaptics' driver version 16.2.15.0, the bug is fixed.

Using firefox 26.0 and the same driver it shows up again.
