You have 22 Ohm gate resistors, so that's worst case 12V / 22 ~ 0.55A so a 1A driver output current limit shouldn't be a problem.
Looks like C14, the chip's decoupling cap, has one pin unconnected. Copy typo?
Never seen C10 / C11, what are they for?
22 Ohm gate resistor looks intuitively too low to me (what's your desired peak motor current?), that would be a very fast switching, and very fast switching -> very high voltage transients. That's around what I would use for FETs with 100-200nC of gate charge, and that gives very few hundred ns switching time.
You should scope your signals, of course... but you have to use a very short GND lead on the probe (the springy thing).
Also.... you have "beefy" caps from VIN to GND *very near* your FETs, right?
