FIFO/Water-Mark and Motion/Idle detection

On the lis2dh (SPI), I went through the data sheet and the very helpful application note AN3308, I was able to configure the lis2dh to detect idle and motion on the INT1. However, I am not able to make this work when FIFO mode is enabled in _REG5 and WTM enabled in _REG3, whenever I have this combination, the FIFO water-mark gets full and the WTM interrupt on INT1 gets generated as expected.

So, is there a way to avoid generation of WTM when the OUT_X/Y/Z are within a certain threshold ?
