Ok, thanks for tell me. This issue happened in the dell precision 5560. When the issue happens, the cursor movements become shorter, meaning that to the same input swipe, the traveled distance of the cursor is like half of the expected one. It's also really hard to make precise movements. But if apply this patch, the touchpad still work well and have expected precise movements
